We are trying LO with the occasional bottle of EBM. Last Monday we gave him about 1.5 oz which he took well. Today he guzzled 5oz in about 15 mins and then BF not long after, tonight he had another 2.5oz in about 8mins and went straight on the breast. I am hoping eventually to have OH give him 1 bottle of EBM each evening but not sure I will be able to express the amount he needs and it seems pointless if he is going to go straight on the breast afterwards. We are using the Tommee Tippee Closer to Nature bottles with slow flow teat.
