In a few weeks I'll be leaving 11 week old EBF DD for the evening with her Dad while I go to an event with a friend. I express milk here and there so there's enough for the odd feed so I can have a bath/visit the dentist/get my hair done but I don't know how much to leave for the entire evening. I'll be gone from around 5 until 10 (if I make it that long) and I don't want to defrost too much and waste it, but I'd feel terrible if my little one was hungry and there wasn't enough ready for her! How many feeds and how many oz a feed? Atm she just has whatever I expressed recently and we don't worry too much about amounts as it's just to tide her over for a short while. Any help would be much appreciated.
