Re: lots of ?
If your baby isn't eating, you need to be pumping to keep up your supply.
Most infants will take 1-1.5oz per hour they are in daycare, in several servings. So, if you and baby are separated for 9hrs, most infants will eat 9-13oz while you're apart.
Pumping every three hours seems to work well for most working mothers.
Can you ask you MIL to not feed baby in the two hours or so before you're expected there, so baby is hungry when you're back together?
Is there any way that MIL might be feeding baby other stuff during the day? It's unusual for a baby to eat 13oz during the day at daycare and not nurse at all in the evenings or overnight.
