Im 100% sure it makes a difference.
Both of my kids were communicating with body language by like 6 weeks. For example I could say “do you want a bottle?” And they would get all excited, or not, if they werent hungry. Part of this is that you have to pay attention to them and respond. The feedback is what helps them learn fast, which they cant get from TV.
(I dint have anything anything against TV, just saying its not a substitute for human interaction)
They are 4 and 7 now and both have a surprisingly large vocabulary and speak clearly.
