For those who had a girl first then a boy what are the major differences?

I notie thtDs is way more active than she was and slo less talkative.Is that normal. More concerned with teh talkataive part. He says ma maand Ithink said it to me in tehmiddle of teh night to come get him yesterday. Also he says dad dad and baba but not for his daddy or for his bottle just randomly.Funnything is he mimics my moms name Barbara.. it comes out like barba.
I dont knwo its seemed like she was saying more things by that age. He was one on 4/7.
