This was my very favorite, most recommended baby product ever. Whether you are out shopping, on a long car trip or just wanting to fold some laundry, this baby is a LIFESAVER. The system is no-drip and is as easy for baby to use as it is for him/her to suck on a paci. I cannot say enough about what a time saver this was. Also, for gassy babies, the system cuts down on air bubbles which is good for baby's tummy! check this out NOW if you are a breastfeeding or formula feeding mom!
