My lovely boy is 7 weeks old and up until about a week ago he would sleep in his Moses basket for about 3 hours between night feeds. This week though he will not sleep at all! He will only sleep on me and if I put him down he wakes crying after 20 minutes and won’t settle. It’s been 4 nights of sitting up letting him sleep on me and I’m exhausted! Can’t keep this up. I’ve read lots about changing nap times and lengths during the day, can anyone give any advice on this? Should he be in more of a routine? I tend to let him decide on naps - is that wrong?! I’m a first time mum and starting to feel like a failure and that I can’t do this. Please help!
