I would like a little freedom from nursing and try to get my baby to use a bottle so my husband can feed her or we can leave her for more than just a few hours with a babysitter (her grandparents). I've tried Gerber Nuk and Advent, but with both she just plays with the nipple in her mouth and doesn't really suck on it. I probably should have started offering it sooner but I missed that so is it too late? Oh, I have also tried both a sippy and regular cup and she struggles with those too. Should I stick with the bottle or the cup? Any ideas how to get her to figure out either?
