I am a 2nd time mom with a 6yr old daughter (always slept no problems) And now a 1yr old boy (he was 1 on 09.12) He started sleeping through from 10 weeks but this last 8-9 weeks he has started waking again. He goes to sleep awake fine but about 2am stands up in his cots and cries till I go in and lie him back down, I do this several times before he goes off to sleep but after about 1hr we start all over again. I don't want to leave him to cry as he wakes my daughter and as my hubby works nights I am turning into a zombie. I work full time so he goes to nursey and only sleeps for about 1-2 hours during the day. I have also noticed he seems grumpy during the day and is not eating as well as he used to so don't know if there is a link. He is a very affectionate boy but he is driving me mad, I need my sleep!!!
