Can anyone help? 12 month old DS slept brilliantly from 9 weeks until he was about 8 months old. Since then he's had a series of colds (which ended at Christmas) and nothing but broken nights. He goes to bed regularly at 7pm and will either sleep through until 5.30am and then refuse to go back to sleep or wake at least once during the night badly enough for us to go to him before sleeping until 6-ish. We use controlled crying when we need to and only get him up when essential, so we're hoping he's not cring for company. We've had about 3 unbroken nights since before Christmas. I'm 6 months pregnant and utterly exhausted. What can I do to get my good sleeper back?!
