Over past few days my dd has been throwing up a few times a day. not always straight after meals or drinks, somnetimes can be an hour or two later. she doesnt seem the least bit bothered by it so i dont know whether to be concerned or not. she has always sicked up after milk but this really smells like vomit and as she is now on solids looks more like it.She is also teething. could it be connected or should i be worried and go to doctor?
