Wind Issues - the other end

Daniel has stinky farts!

I don't recall Blair's smelling like that at that age. Could this be because he's not a 'once a day' boy? Or would it be because of something I'm eating or drinking. They smell sulphuric at times, and now Blair hears him going and waves his hand over him to move the smell - and DH taught him to hold his nose. Not too concered at the moment, more interested in why

Keira let one rip today right in the midwifes face while she was putting her nappy on after weighing her... she also piddled everywhere while she was being weighed!! such a lady haha

Ben's are rotten as well although sometimes he does go once (or more!) a day and then sometimes we skip a day or so. Often I think he has a dirty nappy but it was only wind . Not sure what is causing it
