DS2 is 2 months old and has been a bit of a nightmare with one thing and another. However, the last 3 weeks or so, we have been able to get a bit of sleep at night, since he will get himself off in his cot after his last feed (9 - 10pm ish) and will sleep about 5 hours, though he only goes 3 hours during the day. After that feed, he will then go off for another 3 hours or so.
However, the last 3 nights, he has woken for his feed after the 5 hours or so, then not gone back to sleep and has screamed and cried when I put him back in his cot!
I haven't changed his routine or anything, can anyone suggest a reason for this or, more importantly, a solution?
