My two week old baby has started (today) being very sick after a he has breast fed. He is a hungry easter but doesn't tend to feed feeder ofter sounding like he is sticking in air as well as milk each feed takes no more than 20mins. This said until today his Poos have been regular and yellow and he's put on weight.
However today he had stayed being properly sick after feeds - it looks like quite a lot and goes quite a distance! This has just happened again after his 1am feed and I also noticed his poo has gone green.
What can I do to so this and should I worry (and if so how much)?
