My dd is almost 18wks and I went back to work last week having stored enough ebm for a frozen feed per day and a few spares but she pretty much feeds every 2 hours still and I have found it difficult to express enough now I'm back at work. She also has reflux so sometimes needs more if she's been sick lots. In addition to what I can express (usually 2 -3 4/5oz bottles a day) She is now needing 2 frozen feeds a day (I'm home just in time to stop it being 3!) so my stores are getting low!! I simply do not have the milk to give her. I need to introduce another feed in place of a frozen one so she will have about 3 bottles of ebm (including one frozen one) then be bf when I am at home but my question is whether to introduce a formula bottle when out of what has been left each day or start baby cereal just in the morning and see if that helps. Advice please?
