Have been trying to get DS (18 weeks) onto bottles for weeks, am still BF at night and occasionally during the day. He had started taking up to 4 oz from a bottle and now all of a sudden he wont touch them. My milk had started to dwindle a bit...it's hot and he wants to nurse...milk not really there. Do I just keep going and hope it comes back? Make him wait and bottle feed? Argh. The guilt.
