i really like 6-9 mths but if i had to pick a fave time i really couldnt watching him grow and learning new things every day is just amazing i love that i can joke around with him now and he gets sacasim and the funny comebacks he has i especially love watching him sleep from birth to know i could watch him all night every day is a new day! he has kearnt to play a game on the computer and i was just watching him in amzement how he knows what to do..i put three games up and then minimise them and he can get to which ever one...im such a proud mummy every day
