If the mummy is going to try to fill up baby before she goes out, then her milk is going to come back in fairly quickly and she is going to be either leaking or uncomfortable while she is out at lunch, poor woman. Maybe try a teaspoon or a syringe out of the Calpol? Just trickle it down the inside of the cheek? It's what I do when my doggie needs medicine or won't drink. I don't know really, I breastfed for 6 months and 8 months respective with my two. I loved it, was sore, bleeding at first, but once I got over that bit it was a joy, cheap and something only I could do for them. All their other care could be done by anyone else really, not that it was, but it could have done. Good luck.
