NUK Smooth Flow Pro Anti-Colic Baby Bottle, 5 oz, 1-Pack

I love these bottles. When I received them I was fresh out the hospital and had nothing prepared so I was happy to receive these good quality bottles been using them for 2 weeks no sign of colic as of yet. They work awesome and I love nuk brand. P.s. all the attachment have to be snapped in place before use otherwise if anything is missing it could cause leak. Also I haven't had a baby since 2013 so it would have been nice to know when washing the nipple doesn't separate from the rim. Overall great bottle and the it's soo cool that if your baby milk is too hot in the bottle it turns the temperature device on the outside of the bottle from blue to white/clear looking color when it cools down back to ready to eat temperature it turns back blue.
