You know, Amanda, I've OFTEN wondered the same question, with the added question of 'what did I do to make her like this?'
DD was a NIGHTMARE at going to sleep till 13 months (aaah, the miracle of catching chickenpox!), a 45 min napper till 8-9 months, but also very good at sleeping throught the night.
For over a year, I had to listen to DD scream and cry and scream for at least 30 mins EVERY SINGLE time she needed to nap/sleep, it' nearly drove me to distraction - and then I saw these kids (my brother's being one of them, my firend had another) who would 'just drop off when tired', nocrying, no screaming, nothing - just asleep. I nearly drove myself mad wondering
a) what 's wrong with MY baby that she won't/can't do that?
and
b) what have I done to cause this?
I wondered if I was overanalysing things (as suggested once) and if i just left her alone, she'd be ok - but she wasn't - EVER, and I couldn't bear the crying.
She doesn't sleep in the pushchair and hasn't done since about 10 months old - I look enviously at other parents' out and about with their sleeping children in pushchairs.
She won't sleep on our lap, and has never done (not since outgrowing newborn phase) - I look enviously at other paretns on the for example, plane and see their toddler sit on their lap and gently fall asleep, whilst ours struggles and protests so much that we don't even bother now, she just gets more and more tired and bears it until she's in her bed or car seat.
Sorry for rambling, but just wanted to say that I completely know where you're coming from - and my conclusion now is that it's just the child that is different not anything that we've done.
Next one better bloody behave that's all I can say!!!! :wink:
