3.5 month old eating less?

[MoominJ]

I've noticed this last week that my lo only wants one boob each feed, is that normal?
He's a quick feeder, 5 mins each side but this last week he's only wanted one boob most feeds (especially at night). He eats around every 3 hours

By the way he's a little chunk, over 17lbs at 15 weeks!

I can't speak from experience but I've definitely read at this time they become very efficient feeders so I think it could be quite normal that he is nursing for less time overall (although 5 min each side was already super quick - lucky you)! I think as long as you are OFFERING the other side and he is disinterested then it is totally fine and he is getting enough...especially since he is gaining weight well as you mentioned!!
