We went to the doctor last saturday and rafan only gain 200 gr weight since last month . He looks more skinny and no more 'supitem' . We suspect maybe he had GER (gastroesophageal reflux) which is a common things for baby/infants. Doctor gave him zantrac but then i found out that zantrac is not recommended for babies so i decided to stop giving him zantrac. Due to his allergic, we can't give him baby food so until now rafan only drink breastmilk and formula if my breastmilk is not enough. Now, we feed him more frequently and hopefully his reflux reduce by itself, cause GER often resolves by itself.
