I still let my son wear mittens at night in case he scratches and startles himself from his sleep. But day time we will remove and let him suckle on his own hands. We will file his nails at least once every 2 days so that his scratches won't be too deep. Applying BM on his wounds do help to heal faster too.
I remove at 2.5m but still wear at night when sleeping. I feel that scratching is unavoidable, my LO had a few scratches (around eyes & nose) despite us filing her nails too but usually recovers quite fast.
can actually try putting in zipper swaddle so they don't have the chance to scratch themselves hahah
My baby wore mittens till 3mo.
