Combo feeding cows milk and breast milk after 1yo
My supply has dropped significantly since going back to work. I pump twice at work for an 8 hour shift, and when I'm home breastfeed baby morning, night and before both naps. At work now I cna only manage to pump 40-60mls every 3-4 hours. My freezer stash for daycare and days when I'm at work is almost at an end.
I plan to still pump and breast feed as often as we are now, but I send bub to daycare with 150ml bottles of breast milk and if I'm only getting 80-120mls every day I pump, that won't be sustainable. She needs 2 bottles (300mls) when I'm working in the morning as she often is still asleep when I leave.
My questions is, to "combo feed" with breast milk and cows milk, how should I go about it? I was planning on just putting whatever I manage to pump into a bottle then topping the rest up with cows milk. Should I keep breast milk and cows milk separate? I just worry daycare won't make the right amount, as I've been sending her with 150ml bottles and they always say she had 120ml, but say she drank the whole lot. So obviously they don't pay attention to how much is in the bottle.
What does everyone else do?
