So my 14 week old has suddenly decided he doesn't want to take a bottle anymore. From 4 weeks old we gave him the occasional expressed milk bottle to get him familiar. He took to it straight away and seemed happy on either. We decided to buy an expensive breast pump to replace the manual one and now he has decided he won't take expressed milk from anyone. We have tried allsorts from leaving him with my mum and sister, me leaving the house so its just him and his Dad, milk warmed to various temperatures and different bottles but still no success 
He isn't feeding well on the breast either now. He is so distracted by everything and he is always bobbing on and off (this will teach me to be smug about how easy its all been so far)
I'm really worried as I start my KIT days at work next month.
Any suggestions on what to do?
Thank you
