Aw Hun, I remember feeling the same frustration! My DD is similar, she will only sleep in her pram during the day and it's been that way for most of her life. I've been through times where I've tried to put her in her cot for daytime sleeps they'd end up being 20 minutes max. After a week or so I asked myself whether it really mattered that she slept in her cot and since then it's all been fine. She sleeps in her cot at night and her pram during the day, and above all, everyone is happy and well rested!

Strangely, we're overseas at the moment, and on a whim (or maybe I'll give myself the credit of mothers intuition this time...) a few days into the trip I put her in the cot instead of the pram for her day sleep and she's been sleeping well there for about a week. Having said that I'm standing here rocking her now coz she's not settling today, so it might be back to the pram for us... The only thing you can be sure of is as soon as you get used to something it will change!
