DH is taking me out for a posh lunch for our anniversary next week, his parents will be staying with us at the time, so are going to look after DS (3yrs) and 12week old DD. DD is breastfed and never had a bottle, but I am going to leave a bottle of expressed milk ready in case she needs a feed while we're out. What I'm not sure about is how much to put in the bottle. I have expressed a couple of times and got about 4oz each time, this was early in the morning with very full breasts (just did one breast as that is what she usually has). It doesn't look like much though, so will it be enough? There will be more in the freezer in case they need it though.
