Suck Hands

Sucking finger is baby’s way of soothing itself. U can try substituting it with a pacifier but the baby may not want it. For hygiene purpose, u may want to clean baby’s hand with wet wipes if u find him touching stuff or people around him.

mine sucking her mitten, swaddle, napkins, elephant, basically anything close to her mouth, lol. Still thinking whether to buy a pacifier or not, afraid it will cause another problem (addiction)

Either you swaddle baby, help baby quit this bad habit but you'll probably hear cries alot. Haha.. remove baby's hand everytime you see it. If not introduce pacifier.
