Hello everyone. I wanted to wean my baby from the bottle since birth but it didn't work out. I bought different bottles but she always spit them up. But then I got used to it. And lately, my daughter started taking a pacifier only before bedtime, and yesterday she took it during the day and night. That is, she learned to use it. And you know what? Now I am worried if the pacifier is harmful to her digestive system? Because my mother-in-law thinks so, and I don't even know. I heard that pacifiers quickly digest food, and lactation consultants say to remove it if the child doesn't gain weight. How true is this? Thank you all for your answers
