Your post made me laugh, my DS us now 7 months but in those early days he was able to go days between dirty nappies. It feels like a long time ago already! The record was 17 days. I kid you not.
I went to the docs, saw a bf lady in that time and asked here and everyone said to wait. I know it feels wrong but as long as there are wet nappies, baby is fine generally then it really is fine. By day 17 my patience was wavering. I bought a bottle of prune juice. Got home from the shops, showed it to him, put it on the side and half an hour later, well I'll spare you the details! The bottle is still in the cupboard, not sure what i will ever do with a litre of prune juice!
After that, he was often going 7 days between dirty nappies. Not so these days though!!
