Not sure where to post this. In the afternoons usually when i have my 15 week old baby in the playpen on on the bed next to me we usually have "talk time" where he makes noises and i "talk" back to him. sometimes he is laughing/squealing and then he starts going eheheh like he is starting to cry and sometimes the mouth moves down into a pout. is this a sign of overstimulation? he will only do it sometimes and cry a little bit and then start laughing again. yesterday he did it just before bath time ans after putting him in the bath he was ok.
