I think as long as they are going and their poos are soft and not hard little pebbles there is no problem. Danielle was like that for ages on formula but she wasn't grump like she needed to go more often and the MCHN said it was fine. Now she's on 2 meals a day of solids, 4 formula bottles and 1 water bottle per day I'm finding she's going more often - especially with spinach and green beans!

As I said as long as she's not grumpy because she is constipated and is still going and it's soft I wouldn't worry about it.
