smelly wee?

Stef
I have noticed that my lo has started to have quite smelly nappys shes passing wind and weeing but not been for a number 2 as much. I hve to keep checking her nappy as the smell is as though she has pooed.  She is also not feeding as much as she used to shes having about 4 min feeds and thats it whereas first few months it could be near to half hour
