4 month old fighting bottle?

she just might be teething or have a sore throat or anything at that age they cant show you what it is, have you tried some calpol and a bottle after? dont worry its normal my son went through this seh is getting enough food, i ended up putting my son on solids at 5 months due to this, but best to try the simpler options first teething etc and when she does drink let her have as much as she will take good luck xxx
