It sounds totally normal to me too. My dd is almost 4 now and usually only nurses once or twice a day. But if upset it is way more.

This is a true story quote from bathtime last night.
"I don't want her to pee on me" from my 27 month old as his sister peed on him! He looked very confused why she would do such a thing. One day I am sure he will get her back!!
