Up until this week, my 6 month old son has had fabulous nap patterns, especially in the morning. he would wake between 6:30-7am and go back for a nap at 8:15-8:30, with absolutely no fuss or crying and always sleep for 1.5 hours at a minimum.
This week, that's been turned on its head - we put him down at the same time and after a few minutes of promising silence, he will erupt into screaming and tears, and take up to 30+ minutes to fall asleep, even with a dummy, patting, shushing. And he won't sleep for longer than 30-40 minutes. That then throws the rest of the day out, as I have No idea when he will get tired o how long he will sleep for.
Any ideas as to what might be causing this or how we might resolve it? Would appreciate any input as I am at a loss.
