IN LOVE!! My babyboy is 4 months old & he's learning how to hold his bottle. Still gaining his strength and coordination, but overall these bottles help so much with that, considering the fact that he doesnt have to worry about the milk sloshing around if he moves. Because these bottles allow you to push out the air inside he can be in any position to drink from them & ghe way he has to suckle mimics the breast. The pressure he puts on the nipple releases the milk, rather than it just dripping out when tipped upside down. Just a friendly reminder, if you have never used a bottle like this, push up on the silcone from underneath while you slightly sqeeze nipple in order to release the air.
AGAIN, 10/10!!! Highly reccomend to all moms!! And this is good for any age of baby!!!!! <3
