I just wanted to add that while feeding them you will need to make sure to burp them as well. Thats very important.
Also, I had no luck with the pet bottles or the droppers and so I used a human pre-me nipple. It worked great! I fed every two hours, round the clock, regardless. You want to make sure they are gaining weight. Its best to weigh them daily. Its also better to measure them in "grams" and not ounces to "make sure" they are gaining and not losing anything.
I wish you and your little ones well. Sounds like your doing a good job already! Keep up the good work!!!
