3am wakes

My LO will be 6months on the 3rd of September.

No matter what I do I cannot crack day sleeping, and she’s just become a real catnapper, who I have to put down to sleep every 1.5 hours.

I was just putting up with this because she was sleeping so well at night. However, this past week she has started waking at 3am every single night, and it can be real hit and miss as to whether she will go back to sleep.

I make sure she has a full belly when she goes to sleep, and it’s the same routine every single night. Tonight she woke for a feed at 10pm and she still woke at 3am.

What can I do to help with these 3am wakes? Please note we put her down awake and she can self settle (she just can’t link sleep cycles during the day, but again, I don’t care so much about the day sleeps. So long as she sleeps at night).
