Oh guuurlllll
My littley is 14m. She's never never a sleeper. Twice in her life we've had a sleep till 7am. Otherwise we've been up at least once.
A good night for us is 7.30 to 4am when she has a bottle. She then goes back to sleep with me albeit disrupted sleep for a couple of hours.
Lately she's been up at 1.30 too. Sometimes a visit to her cot and a there there and she'll go back herself. But usually not and in she comes with me.
We do have a chilly house so do wonder if she wakes up more if cold.
She will NOT go back to sleep after about 3am without a bottle. Tried it all. Seems to be genuine hunger.
She can self settle fine. We put her down awake and she does the rest.
We've had every sleep regression going over her little life. Guess this one is as she's walking a bit now. But we never seem to finish one before the next starts
I don't think there's a solution, although if you found something that worked I'm all ears. Just want some mummas to tell me you came out the other end. Or still in the thick of it with me.
PS I get some support but hubby has full on job and I only do 16hrs a week. He's terrified of co sleeping and hates that I do it (but gets it). He won't do it and I get that too. So he can help at the midnight/early hours self soothe point otherwise it's me!
