For the last few days my dd has not been drinking as much milk as usual, so far today she has had 15oz including her night feed, she will only take one more 5oz bottle maximum today then she sleeps till 3.30am ish. She usually has around 27-30oz per day (inc. 1 night feed) she had also been sleeping a lot more and being cranky when awake. She is a bit snuffly, could this be a reason why? What should I do, when I offer her a bottle she cries and pulls away. She's 15 weeks, I will probably see my HV tomorrow but any advice/experience is appreciated! Thanks
