Re: When do I HAVE to start?
You can either keep trying bottles or decide that it's not really going to be fixed by a perfect bottle. With my first daughter, it was pretty obvious that any bottle was a problem so we just stuck with the one that was most convenient to us. My second daughter was a little more relaxed, and we did find a bottle that was more to her liking.
With the playtex did you try the latex nipple?
I was so stressed out about this with Lilah. She wouldn't take the bottle at all. It took about a month, and I was only working three days a week and she finally started drinking out of the bottle. She never did drink much but she drank enough that I felt ok about it, especially since she nursed all night long.
