My friend and I babysit each others' 5 mo babies regularly for a couple of hours and swap bottles of expressed milk on the doorstep before running out to supermarket / hairdressers / have an hour baby-free / whatever.
My mum asked me the other day why I don't just bf her son when he's at mine. Really not sure how I feel about this, although it does seem more logical than fannying about with heating a bottle, etc.
Does anyone do this? How did you raise it in the first place? Am quite worried that if I raise it with my friend she will be horrified.
