My baby has never really spit up right from day one she took 2 oz and could go for more and then week 1 she would take 4 oz and still could go for more. All night after her feedings shes been spitting up and when she does all her bottle comes back up through her mouth and comes out her nose. How can I help her cause after she spits up she's in so much pain
