Neither one of my two kids took to the bottle or pacifiers very well, and after trying about 5 different shaped nipples/brands with my first, we finally found the Mam/Sassy Brand pacifiers AND bottles were the most readily accepted....I think it is because the nipple on the bottle and the paci are somewhat flattened like the breast nipple gets in their mouth. Both my son and my daughter do /did well with these, and they hardly have a burp at all with the bottles which have an anti-gas valve in the bottom (which are also BPA free, BTW), another plus is they don't drool milk or formula all over themselves with this shape nipple the way mine boh did with all the "cylindrical/traditional shaped" nipples we tried.
When they are little/first starting with the pacifiers, you have to hold them in for the baby, for the first minute or so, and once they start to suck well, tug it a little as if you were going to take it away, and they will usually suck harder.
You can get the bottles at Walmart online, and the pacifiers at nearly any store like Walmart, Target, Walgreens, etc, they come in a newborn (teeny tiny) size, then 3-6 months, and then 6 mo +. Have Daddy or someone else start introucing the bottle when you are not around, and once they accept it, try to be consistent and give a bottle wach day, to keep them used to it.
Good Luck!
