My lo is 4.5 months old and just over 2 weeks ago, we changed him onto Mam size 3 teats. He was falling asleep on the 2's, generally just playing about with his bottles, not finishing feeds and I think he had just generally outgrown them.
Since being on size 3, some feeds are hit and miss but he's generally doing really well on them. Finishes most bottles or only leave half an ounce or so. Has started to take more in general but we have noticed he has started to spit up more. It's not a lot, I know it can often look like it's a lot more than it actually is. He doesn't seem uncomfortable at all, it's just the spitting up and he also has a bit of a cough too.
Any advice? We really don't want to go back to the 2's as he was struggling so much with them. Feeds have been so much better since we changed up.
