Any form of communication is important be it talking, pecs, sign language , or adaptive aides. As your child gets older, you don't want him pulling you or grunting for everything that he wants. It gets very frustrating for the child and caregiver, when you are always guessing and he/she has no other means to communicate. Non communication is one of the main reasons for anxiety and mektdowns

Everything happens in God's timing. Continue the therapies and work at home with your child as much as possible. I find that labels, giving them a chance to say words or phrases before you give them something, pictures, books and all those things help. I will tell you that my child started talking more clearly and talking more period, a few weeks before his 4th birthday. The professionals help, but I believe that time you spend with them and praying for them, is key.

Hi...i am a mom of a 3...almost 4yo😊....my son is non verbal as well.(he does babble)
Something that i have carried with me from the get go maybe because of my own disabilities i suppose🤔....is to be supportive, get the help available to you for your son and know that being an advocate and your childs voice is sooo important....i have found ways to communicate with my son that have also helped..like letting him lead me to what he needs or paying attention to his gestures and body language.
The way i personally look at it is i am going to help my son in any way i can...but i wont dwell on what he cant do right now(of course I would be delighted if he spoke one day,but i cant control every situation)... try to see the world from his piont of view..not how others view him.
I am in no way saying you view your child as anything but wonderful...i am simply stating my own views and sharing them with you😊i understand every parent is going to have his or her own views and opinions...these are just mine.

I did have the same problem. At first it was really hard I had to follow him around all the time and spent a lot of time just pointing at whatever it was he was looking at and saying what it was (single words only not “the big blue block” simply “block” or “blue” or whatever the target word was). It wasn’t until i got really into the Laura Mize stuff that I learned how to engage him better by making it really really really rewarding for him to give me attention. I’m lucky my son loves big over the top expressions, tickling, and motion, so I was able to slowly start gaining his attention by playing simple social games with him but being overly enthusiastic and fun with them. I would do things like the belly game where I would blow raspberries on his belly and say “belly!!! Belly!! Belly!” Really loud and happy to where he would laugh. Row row row your boat where the lyrics at the end were “close your eyes and scream!” And when I would cover my eyes and scream with a surprised expression! Then there was jumping on the bed where I would hold him by his arms and say “jump jump jump! We’re jumping on the bed! Jump jump jump!” Anything I could do to get him to enjoying giving me his attention. It felt awkward at first because I was never a big baby talker but I basically transformed myself into being really good at talking in a fun way. All of those skills I attribute to becoming obsessed with Laura Mize podcasts and her book teach me to play with you. I swear I am not payed to promote her or anything I feel the need to say because I talk about her so much but she really was my inspiration. Something that might help if you can find them in the podcasts is listening to the 11 skills toddlers need to learn to talk. I think it’s in the episodes 280ish somewhere but attention span is also the topic of one of those shows. My little boy was extremely busy and wouldn’t even look at me but a few months 3-4 months of me working on those fun engaging activities and he was dragging toys into the bathroom (while I was on the potty) for me to see and holding them up for me to play with him (something he NEVER EVER did before). And he was about 2.5 going on three when he really started engaging. Even now I have some attention span issues I can get him to engage in one activity for maybe up to 20 minutes(if he is interested in what we are doing) but as I’m sitting here typing this to you he won’t stop talking to me or leave me alone. Never would have been possible without those 11 skills I worked on. Happy to help as best I can I could talk about stuff like this for hours.

Hello! I know exactly how you feel!!! My son was nonverbal until 26 months old when he started saying his first few words “ball, go, eat, drink, more” it all came very gradually. After his first word “go” at 26 months I kept pushing and trying to teach him new words. It was frustrating, trying to gain and hold his attention, being so repetitive over and over with the same words over and over and over again. I used aba techniques A LOT! So like i would be playing outside with him with the water and I would say “say water!” And if he made any noise at all I would spray him with the hose. It felt hopeless for a while, I wondered constantly if he would ever be able to make sentences or tell me how he was feeling, but trust me when I tell you I never ever expected my son to be as verbal as he is today. He is four now and won’t shut up! I remember when he was two and people would say they wished their kids wouldn’t talk so much and I would get really sad and think to myself how lucky they are and how if my child ever talked that much I would never wish for him to stop. Well, I am there now. He talks so much and asks so many questions it makes my head spin, and only two years after he was nonverbal. It is great that your son is echoing some words! That’s great! Set up some verbal routines like ready set go! And be very repetitive with the same target words throughout the day and he will pick them up after a while and eventually, though it may seem hopeless his language will most likely snowball like my sons did. He went from like... 5 words one month, then 20, then five or so months later like 200 and now there is no way to count how many words he knows. He speaks in full blown sentences... I mean they aren’t perfect sentences they’re all backwards and mixed up and stuff but I know what he is saying :) keep the faith and keep trying! Also I found that in the early days when my son was nonverbal I found a lot of help listening to Laura mize teach me to talk podcasts. I learned so much from her I even have like four of her books. She helped me teach my son better, so if you have time, check her out.
