I'm at a loss with DS's sleeping (2nd DC). He is almost 6months and his sleeping took a turn for the worst at the usual 4 month mark, but has been deteriorating ever since. He now wakes up ten+ times in the night. It is driving me bonkers. He is the lightest of sleepers even in the daytime and sometimes exists on only one 20 minute nap all day. He has been co-sleeping since birth and at first he was brilliant - started sleeping through at ~3 months (7-8 hour stretches). Now he is awake sometimes 10 minutes after falling asleep and this repeats over and over in the night until I'm threatening to send him out the foxes! Good thing he is so deliciously cute.
We are going to move him to a cot in DD's room this week to see if it helps. DD was the opposite in that for the first three months she had colic and was impossible to get to sleep, then suddenly at 3 months she started sleeping through and did so ever since. I'm not sure we learnt any lessons from that so hoping to get some good advice here. Any suggestions welcome.
