Re: best bottle?
I know your baby is still young, but I find it might be better to start introducing a bottle earlier a little at a time. With my LO I introduced the bottle while he was younger and he had his tolerance for the bottle. I stopped using it for a while because I was primarily at home and he preferred the breast now he is 4 mths and refuses the bottle all the time. If you do introduce the bottle a bit now just be consistent with and start off small. I'm feeling the burn now.
I have tried many bottles and now im trying the playtex ortho bottles with the drop in liners and i find he is beginning to take to it. the nipples are softer than some others and might be giving him the feeling of squishiness like the breast.
