Girls, hello everyone! Could you please tell me how to clean your babies' noses? Sometimes during the day they get stuffy and I use a suction bulb to clear them. I read that it's harmful now. But I don't know what else to do. The baby is still too young to clear his nose himself or even blow his nose properly. It's hard for him to breathe afterwards, especially before bedtime and in the morning after sleep. You can't recommend nasal drops with breast milk either.
