How much milk do you send to the sitter?

Renae
Mamas that work and breastfeed - how many ounces of breastmilk do you send to the sitter's/daycare?  Our little one is just under 4 months.  Everything I read says breastfed babies generally consume about 3 oz per feeding, so I've been sending enough for 4 feeds each day.  Our sitter also has frozen milk in case she needs it.  I'm just wondering what other mamas send. Our little girl is healthy, happy, and strong...but she is so tiny.... I don't want to overfeed her, but I'm curious what others are doing?
