I returned from my 7 month maternity leave last week and my son will not take a bottle of pumped milk. Most days I have driven to the babysitter's house during my lunch to nurse him so he won't starve. As work gets busier I know I won't be able to do this every day. Am I setting my baby up? Should I stop? I think he's lost some weight even though I try to make up for it at night.
