I'm not sure what happened, my baby who is 5 month old went through the 4 month sleep regression and started needing to be rocked to sleep. Before this she would self settle. Now she has changed again and the last 4 nights it's taken me around 1.5 hours to get her to sleep and she has woken so much during the night. I know she could be teething and she is also EBF and only has a poo once a week which must be uncomfortable. I'm not sure what to do for the best and as a first time mum this last 4 nights has knocked me for 6 with the lack of sleep and made me doubt what I have been doing.
