instruction: hello doctor my oldest son is years old he understands everything you say to him but he refuses to talk he used to say a variety of words and now he only does animal noises and a handful of words I would like to know what I could do in order to encourage his vocabulary or if I should be worried about it in the first place I am also wondering if his decreased vocabulary and stubborn behavior are linked to the arrival of his baby brother a year ago I am currently trying the apps speech blues and abc mouse he also likes puzzles and games but he will not sit for the songs or story telling any advice would be appreciated
output: hi it seems like a regression of speech is there with normal receptive skills and affected expressive skills rather than finding the cause now focus on how to improve the condition apps are good but not in the initial stage start with some interesting real life activities to extract some simple utterances first do not give anything without his utterances even if minimal it should be there pa pay in a musical manner like other phonemes also start extracting he will surely enjoy from this go to combining like pay tea too then potato then tell see we will cut potato cut the real potato and show him get a video consultation with me if you want to get the demonstration for a better understanding implement these techniques and give feedback on this thanks
