1st of all I hope by milk u mean ur own breast milk..if in daytime child is taking properly and in night time child is vomiting..then there has to be some issue In technique in night..please ensure proper burping at night too..feed only when baby demands..ensure head end of the baby is slightly up than leg end..what was the birth weight and what is today's weight..If problem persist inspite of all efforts then visit near by pediatrician

Hi, As babies grow older the feeding time reduces and duration between feeds increases. So feed on demand only
