Lemon and seashell patterned swaddles. Purchased on Rakuten. - Size: S (up to about 3 months) This type prevents the baby from putting their hands out. I should have bought another type, so I haven't used these much. If you want to try a swaddle to see if it suits your child, please feel free to try it as it's inexpensive. It can reduce the startle reflex, so it helped a lot in getting my baby to sleep for longer stretches. I think it really depends on whether it suits the child or not. Thank you for looking.
