I have a 4.5 week old and she will go 3-4 days without having a stool. I breastfeed 10-12 times per day and she has gained 1 pound in 2 weeks, so I know she is getting enough. She also has a ton of wet diapers. She's very gassy and often grunts and looks like she is in pain, but she never has a poopy diaper. I talked with my ped and she suggested a teaspoon of a stool softener in a bottle with breast milk, but that makes me nervous. Any suggestions?
