Thumb sucking?
Hi all! FTM here :) My baby is 3.5 months old and has recently started sucking her thumb a lot to self-soothe. I know hand sucking is developmentally normal at this age, but my concern is more about sleep.
During the day, she sucks her thumb aggressively while I’m rocking her to sleep for naps (she’s also been protesting naps a lot lately). She spends a lot of time sucking her hands when she’s awake and even tries to put her hand in her mouth while drinking her bottle.
At night, she doesn’t suck her thumb to fall asleep initially, but she does use it during partial night wakings to connect sleep cycles. Yesterday, she was in active sleep from about 6–7 a.m. and sucked her thumb for almost the entire hour.
We almost never used a pacifier before because she settled well without one, although I know she’ll take one if I offer it.
My concern is that thumb sucking will become a sleep association that’s hard to break. I’ve read that pacifiers are generally easier to wean than thumb sucking, so I’m wondering if I should start introducing one now instead. On the other hand, I don’t want to create a new dependency if it’s not necessary. Should I try a sleep sack with fold-over mittens?
Has anyone been through something similar? Did your baby eventually outgrow thumb sucking on their own? Did anyone introduce a pacifier for naps only, and if so, did it become something your baby needed overnight as well?
Thanks!
