I have an 8mo DS. He has always put everything in his mouth. I understand that this is a way of learning the environment around him and that a lot of babies do it. However, at 8 months old, he shows no signs of stopping this and it is becoming quite frustrating. If we read a book he spends the whole time trying to prize it off me to chew it. Same with any toys/household objects etc. I find that I set up games/activities only to despair 2 minutes later as he won't engage with any of it apart from putting it in his mouth. I see friends babies of the same age turning book pages and playing games. Anyone else have/had a baby like this....when did it stop?!
