Which brand of feeding bottles are good for a 6 month old baby ?

A. If u r parallely breast feeding then u should choose the right bottle which goes well with breastfeeding otherwise baby will start prefering one over the other. Philips Avent natural feeding bottle and Medela calma bottles are designed to give the same feel as feeding from the mother so that the baby won't resist breastmilk while parallely feeding through the bottle and vice versa. It worked well for my kids. You can try using any of these bottles.
