The ergonomically shaped fisher price feeding bottle is a must for all parents and babies. The bottle has a shaped style to it to make it easier for little hands to hold as they become independent in their feeding. The markings on the bottle are clear and easy to read and also show pictures of the different teats so you will always have a reminder of what teat they need to move up to. The lid on the top of the bottle is designed with safety vents either side. The bottle comes complete with the first stage slow flow teat.
