Have dd2 who is 20 weeks, she is exclusively breastfed, she's never had anything else at all, she's a good efficient feeder from day one, however, she has started screaming at pretty much every feed! She doesnt take much before the arched back sobbing, squeeling yelling, punching the boob starts (probably feeds for a max of 1 or 2 minutes before she starts!) Last 2 nights have been the worst, she started these meltdowns at about 4pm and proceeded to pretty much exhaust herself to sleep by 10.30pm with small 5 minute naps here and there. I cannot for anything figure out why on earth she's started all this, she has been nothing but an angel from the moment she was born, have maybe only once or twice heard her proper crying, until now that is!!!! What could the problem be do you think?? im totally stuck and knackered!
