"How can I stop my 7MO baby waking for an hour each night happy and wanting to play. She is well fed (around midnight) and clean, just wanting to play!" - Katia, Yowie Bay
Lucky you mum, party central in the middle of the night!
If your daughter is happy then I would just leave her in her cot, don’t go into her and should I assume she does put herself back to sleep? If this is the state of play then I imagine this will be a phase that will pass as she becomes bored with herself in the dark or just learns to put herself back to sleep more quickly.
I would also ask if your daughter has a fairly consistent day routine including 2x sleeps and she is put to bed about the same time each night after her solids, bath, milk feed and bed? This will set her up for the best quality sleep overnight including her overnight feed….you could also try bringing that overnight feed forward to say between 10-11pm (dream feed) then it would be reasonable to expect her to be able to sleep until next morning to start the day any time on from 0600-0630 (and 7am would be marvellous!)
Hope this guidance helps, your baby sounds like a fabulous, happy, party gal!
