Crawling and won't self settle - what to do?

[Suchanamateur]

DD is 8.5 mo and in the last 4 weeks seems to have finally got self settling. Not necessarily long naps but not lots of patting to sleep (helpful since I have a 2.5 yo too). But she learnt to crawl a week ago an in the last few days has been totally hyper at nap time - crawling, sitting up and clapping. Very pleased with herself but not sleeping. Then v OT by end of the day..

I'm loath to re-start the patting but not sure what else to do. Leave we in there till she eventually sleeps?

If this is a phase, how long will it last. Don't remember it with DS but then I do seem to have blanked a lot of stuff out...

I've decided to in back to the patting now that dd has learned to pull herself up. I leave her to mess around on her own and only go in once she starts getting upset. I lie her down again and if she stays down I rub her back. If not I leave her to it again. Repeat as necessary (usually 4 or 5 times).

Oh I so need to do something about this for DS2 (8m). He has been crawling a cruising for a little while. Had self-settling down pay until then, have ended up settling with a bottle as last resort and now habit as he has awful seperation anxiety. I can't leave him in his cot without hysterics from him.

Sorry to hijack your thread OP but any advice would be appreciated.

For what it's worth I wish he had settled with patting and wouldn't hesitate to go down that route if I had a time machine.
