my baby will be one month old on 19th January. earlier I use to feed her with formula milk 25ml every 3l2 hours then I increased it upto 30ml every 2 hours but now I am giving her 50 ml every 2 hours still she gets hungry in every 1 hour. how much should I feed her now? I am very much concerned if I overfeed her as she is already having gastric issues.
