Keep talking. When he comes to you ask him questions like what exactly he wants and how many for example..read out books it really helps.

Hi as the baby is 2 he needs to form sentence and speak by now. Please keep talking to him and ask lot of questions, take him to the park or play area where he can meet older kids. If there is any screen time with tv and mobile please stop it<br>

Nothing to worry.. keep talking to the baby.. also play with him ... Hide n seek will be good.. keep talking and singing with the Baby..
