We spent ages winding her, trying to give her her dummy (which she kept spitting out), swaddling her, taking her into a dark room, rocking her... After an hour I eventually tried more milk, and she was off to sleep after an ounce
I'm happy to give extra occasionally, but I don't want to give it all the time if she's going to be overeating; I'm worried about her getting overweight - my OH is overweight and he doesn't want it happening to LO. Trouble is, once you make a habit of giving extra, the baby will rely on it, and I don't want her to rely on it unless she needs it.
I may take her to be weighed today and ask the advice of the HV. You're right that it's all a guessing game.
I would love to demand feed her, but so worried about her gaining too much weight!
