My ds (Three months) is breastfed and goes to bed every night at sevven. My husband wakes him up at eleven and gives him one bottle of formula. He then wakes again anywhere between three and five before the morning. Last night my dh did the middle of the night feed with formula (It was actually fivve thirty - lucky him!) I would like us to keep taking it in tuurns but will I affect my breastmilk if I ony breastfeed every other night? Apologies for the gaps that are in the words in this post - something wrong with my keyboard!)
