Our 18 week old (slow weighting gaining) DD has generally been an angel in the evenings, feeding relatively quickily and going down to bed always roughly at 7pm. We feed on demand, but the pattern has settled down over the past, oooh 2 months, to a feed at 4pm/5pm and then the bedtime feed at 7pm (then another at 11pm).
However, in the past week her 7pm feed has become really fractious - with her squirming, coming off the breast every minute or so, and protesting loudly if kept on. We switch her to the other side when she gets really mardy, without much success - and recently it's taken us upwards of 2 hours to get her down.
Yesterday she was having a real squirm, so in desperation we thawed 3oz of frozen EBM and she guzzled the lot in one go - wanting more milk afterwards - so is she hungry? If so, why isn't she staying on the breast long enough to get it? Is it a supply issue? If so, why now? It's been a fairly steady pattern for a while now. We initially thought it might have been a growth spurt, but it's lasted a week now...
Any ideas gratefully received!
