I am currently supplementing with formula as I do not have the best supply that is not increasing after trying pretty much everything.. So I have decided to switch my son over to formula once he is 2 months. I want to continue pumping and put a certain amount in bags and freeze them to be pulled out and added to his formula once a day until he is at least 3 months.. Problem is that I only produce about 3 oz and his intake just keeps getting higher and higher.. Is it worth it to continue pumping to only be able to provide him with about 2-3 oz bottle a day? will his tummy get upset as it becomes more used to the formula? I read that any amount is worth it, no matter how small.. Suggestions?
