I've heard about sleep regressions and in all honesty I don't think we have had one so far but last 5 nights dd won't settle.
Dd normal routine would be 7pm feed and bed. In a cot in her own room. Wake up 5.30 ish, have a feed and come into our bed and go back to sleep for an hour or two. If she woke in the night she also used to settle herself back to sleep really well.
The last 5 nights have been hard. Dd won't settle at all unless she is cuddled into me or dh. Does this sound like sleep regression and it will pass or do I need to look at trying different routines?
