If you have to use platter, the liners are the best because they eliminate all air which reduces SIDS. However, my fave is the nuk system :)
I have a thing about old bottles so after 2 months of use I got new ones. My little one was about 4 months then and not sure if that makes a difference but I got the walmart band really cheap and she didn't have a problem. Not sure what we used first as they were gifts but I remember using the liners and loved them. I would even use them in other bottles when going out. But I was giving the liners and never got more.
Thank you :) I'm planning on starting baby stuff shopping soon as I get through my first trimester. I have to buy all "new" with this one because I gave a lot of my stuff to my sister when she was expecting. And I used " " because I mean fresh moreso than new lol. Theres second hand baby shops I love to go to.
I've used both. I like the ventaire ones the best though! My son seemed to like them the best as well!
