Yup Fi, generally I apply that rule too. Certainly at home or mums house. If I were out somewhere like the shops etc, then no way. Hey I'm even fussy with the kids touching the hand rail thing on the escalators because of germs

Have to say though, I'm alot more easy going with the little ones than I was with my first bub.

ETA, I have one of those seat and handle cover things for the shopping trolley, no way is she getting her mouth near that handle ....
Fi, you do know dogs pee on grass dont you??
