My son has been a great sleeper up until 2 days ago. He is 7 months old and has slept through the night consistently since 3 months old, it's been wonderful! Last night we went to lay him down though and he just started screaming bloody murder... My wife comforted him and then went to lay him back down, and as if we were putting him into boiling water, as soon as he touched the bed screaming again! Took and hour and half to get him to sleep. Tonight rolls around and exact same thing is happening.

Any advice would be appreciated. I know many have not great sleepers and this sounds not that bad but we are just confused as to why all of a sudden he is doing this now. Thanks!
