Not sure if this is the right board for this but any advice welcome!
DD is 9 weeks and in the last 3 days has started chewing earnestly on her fist and really working on getting her thumb in her mouth. She loves sucking but rejects a dummy so this may ultimately help her self settle (whether we should be trying to prevent it is moot as she's quite determined).
The problem is any time she stirs at night now she brings hand to mouth and wakes herself in her frustration at not being able to get the thumb in/keep her hand there for a suck. I've been awake nearly every hour overnight with her, having gotten a taste of a few glorious 4 to 5 hour stretches of sleep previously! She'll only settle with a BF so she's getting a lot overnight.
Anyone with any experience of thumb-suckers? How long did it take them to master it and get past the frustrated attempts? At this stage I'd just like her to go ahead and do it if it'll help!
