#AskTheExpert my baby was born with birth weight of 3.115 kgs...she was kept in nicu from birth till 11 days and today we went to take the vaccine but her weight was 3.820kgs ....so the nurse told us to come after 2 weeks as the baby weight was too less to take the vaccine....so the vaccine which need to be given on 1 and half month will be given on 2 months..so will it be problem? and what may be the reason for not gaining weight as far as we know she is breastfeeding properly as she is not crying much and she fill content... and she passes stool for 5-7 times
