It's pretty common for some babies to do. It could be a phase, and he'll start taking more at daycare. I wouldn't be worried as long as he's nursing plenty while with you. A minimum of 8 nursings a day is what you should shoot for. Just keep watching his diapers, as long as he's staying hydrated I wouldn't worry.
