My MIL watches J on Mondays and my mom does on some Fridays. They both watch him in our home.

He goes to daycare Tues-Thurs. At daycare he eats 3-4oz bottles normally at 10, 1, and 4. When the grandma's watch him, he's normally finished these bottles around noon and will have 2 more in the afternoon. Anyone else experienced this?

He also normally takes two 2-3 hour naps at daycare at home, we're lucky if he takes two 1 hour naps.

I pump but can only get 12 oz a day so the last 2 end up being formula.

Is this because he's more comfortable at home or are they just over-feeding him?
