my baby is one month old. he is not able to suck milk from Philips avent which bottle should I use...and if I'm giving 60ml milk one time how much time it will take to finish the feed for baby

A. Madam actually you are using one of the finest brand no brand is better than fits honestly telling you I am also you are giving ample of amount of milk to the child should be about 30 ML in one go so I would just say just check the size of the hole in the nipple I hope your child is easily able to have it because that is what is meant to make the difference and also what size bottle are you using nipples should be comfortable and kids friendly as per the age
