HI. I have a 4 1/2 month old DS who I am leaving for the first time tonight (with DH) to go to a party. I'll be leaving at 6 and back about 11.30pm. He is exclusively brest fed and although we've given him the odd bit of expressed milk in a bottle to make sure he will take a bottle, he's never had a whole feed from one. So, how much expressed milk should I leave? I've no idea how much one feed will be for him. I think he would probably usually have 2 feeds in this time so want to have enough for that plus extra incase he's particularly unsettled since I'm not there with the actual boob! Any advice appreciated!
