My friend has always been very smug aboout how good her baby is in all honesty her baby is an angel she sleeps very rarely crys and will just sit happily entertaining herself, my own little monster is the oposite he is a terrible sleeper screams his head off if he doesn't get his own way and wants to be played with constantly. She loves to point out how her DD is just very ahead of herself and naturally 'good' also how DS just isn't good at things, and my favourite how she couldn't cope with such a moany baby as DS (she actually said that). She also likes to tell me how i should try to teach DS how to do things then he will come on as fast as her DD, i just let him go at his own pace i don't worry about what he's doing much.
Now however DS has 'beat' her DD on lots of things sitting up, clapping hands, rolling, my friend was very disappointed in this but now DS is crawling, pulling himself up and starting to climb she's suddenly started saying 'oh i'm not worried every baby is different she'll do it in her own time' (my usual line) so a total turn around. DS is not specially advanced he is doing things when he should just turned 8 months so is pretty much on track her DD is on track too just now as quickly as DS, I think it's a lot to do with their personallitys DS is a get up and go type and her DD is a very chilled out laid back type.
Now WIBU to be totally smug and boasty in revenge? Sorry this is a bit all over the place typing as DS wrecks the house!
