Hello! I just need some advice on monthly budget for formula... I'm currently pumping my milk and bottle feeding her and sometimes we supplement with formula too. I need to get back to work in 15 days and we decided to switch to formula completely. We are currently using enfamil newborn formula for our 8 week old baby girl. Any idea how much a month to month expense of formula will be? We are on a scheduled budget right now so any advice would be greatly appreciated.. thank you!
