I sent a 5 oz bottle to daycare. DS only ate 1/2 oz of it. Can I send it tomorrow or dump it? It was warmed to room temp, fed 1/2 oz then back in fridge. I hate to dump 4 1/2 oz and I don't really want to feed him it tonight, I don't feel like pumping and, he just got his shots so feels like being at the breast, not bottle.
