I returned to work two weeks ago. My DS is 10.5 months and my DP is taking the last 8wks of parental leave to look after him (until he turns 1). I have always breastfed. DS has always happily taken a bottle of expressed milk,or formula (from about 7months), and has had one bottle a day. however since I returned to work he will not take the bottles, or a cup of expressed milk, formula or cows milk! He will only take milk from me first thing in the morning and when I get home about 7. He eats really well and love drinking water but I'm worried he isn't getting enough milk. Anyone have any advice or ideas?
