My son is 6 weeks old and due to a number of complications, is being fed a combination of formula and pumped breast milk from a bottle. I'm pumping 10-12 times a day to increase my supply, in hopes that we can get him back on breast milk only and with the goal of getting him back to the breast without the bottles. Right now he's getting maybe 1/3 of his milk in formula and is gaining weight like he should be. He has lots of very wet diapers, so I know he isn't dehydrated, but he hasn't had a poopy diaper in 2 days.
I know diaper output slows when babies get older, but I wasn't sure if now was about the time that should happen or if it might be a problem. He's had this happen before, he'll go a day without one, then have a major dirty diaper, then he'll have 4-6 more dirty diapers that day, then skip another day or two. His poops are all the yellow, seedy looking stuff I was told to watch for. He seems more squirmy than normal, but doesn't seem to be in pain or upset. Should I be worried? I've heard that formula can constipated babies and I just really hoped that with so much breast milk in combination would prevent that. Any thoughts would be appreciated!
