DD1 is having behavioral problems, we are pretty much going through hell with her right now, but I think slowly we are getting somewhere - but I didn't drink coke with her. She was the by the book baby. 4 hourly feeds etc.
She was born 7lb 5oz, 50cm at 41+1

DD2 had colic pretty bad. Would scream til 2 or 3 am every night, & has always caught everything going around - had Rota virus & chicken pox at 6 months. & has an innocent heart murmer. Is & has always been a rat bag, but is a bit of a tom boy. That's just her personality. Drank coke with her.
Born 8lb 9oz, 50cm at 41wks

DS has been a perfect baby. I mean perfect. Has never really cried for no reason. Does still feed pretty much every 2-3 hours. Excellent sleeper. Started sleeping through the night within the first week. Would go to bed around 8 or 9pm & sleep til 4am.
He usually wakes up around 3 now, but goes straight back down after his feed. Has always done that. I can't believe how perfect he has been. Drank coke with him.
He was born 8lb 7 1/2oz & 52cm at 39+5

So they were all very healthy sizes & very different as babies.
