I went through a stage with DD where she was doing the same thing with her day naps - waking around 45mins in. A couple of times I offered a feed and she took it like I hadn't fed her for the whole day It only lasted a couple of days and then she fell back into her original routine ... made me think she might've gone through a growth spurt so needed the extra 'juice'..........do you think a growth spurt might be possible??

I am a bit of a routine chick as in I will wake DD up at regular intervals for feeds but that's just me and it's not for everyone, but if it is a growth spurt it could be worth a shot just for a couple of days to give your little one that extra fuel to get her through (if it is a spurt! )

I hope this settles for you soon and I hope you get some rest hun!
