hi A., im not sure what to say about the napping, ive always just let them call the shots when it comes to sleeping at such an early age. remember that they go through growth spurts pretty regularly, and when they do, they will sleep a lot and eat very little, then the reverse. just watch her wet diapers to make sure she is not dehydrated. as for the nursing, if you want to keep nursing, i strongly suggest that you do just that, keep nursing. the more bottles she takes, the less milk you will produce. if you are only nursing her twice a day, you are only going to produce milk at those times. it takes a while for this to happen, its not too late if you want to boost your supply back up, email me if you want to know how to do this, its not a big deal.
although there may be a couple of new ones out there?, as a rule formula is NOT sweeter than breast milk. taste them, you will see for yourself. just smell them, that should give you an idea of what the formula tastes like. the reason that a lot of babies will prefer the bottle over the breast is that it is less work for them to drink from a bottle, they can get full more quickly. they cannot build up the "suck" strength they need to get full as quickly as they want to from the breast if they do not breastfeed enough to do it. especially now that she is bigger and more active, she needs more, so if she cannot get it at the breast she will want it from the bottle. if you keep breastfeeding, she will become a better, stronger, more efficient nurser very quickly. by the time my kids were a year or so, they would empty a breast in under 10 minutes, they get very good at it.
if you cannot, or do not want to, or she does not want to continue breastfeeding, then go with the formula, and you can continue nursing just twice a day if thats what works for you both. that was how my son weaned, he really just wanted the comfort of nursing when he woke up and went to sleep, he did this for about 3 or 4 months before we weaned at 18 mos.
and as for wanting only formula and not breastmilk from the bottle, remember that they do go through phases like the other mama said, this certainly wont be the last... also, just make sure that you are storing the breastmilk properly, it could be spoiled and you dont know it, that would certainly explain her not wanting it. taste or smell it, there will be no question in your mind if it its spoiled. i had a freezer full spoil on me, i dont know how it happened, maybe the freezer door didnt close all the way at one point and they defrosted and refroze? i dont know, but my daughter kept throwing the bottles on the floor, when i finally tasted a bit and almost puked, it was horrible,had to trash it all... that hurt!
.....i am a big advocate of breastfeeding, i think it is best, but i also feel even more strongly that it is MORE important that you both be happy and comfortable when feeding, and if giving formula some, most, or all of the time is the way to do that, then thats how it should be. people stop or reduce nursing for many different reasons, different things work for every family and situation, the most important thing is that you are all happy and stress free about feeding. if you continue to give her some breastmilk, thats wonderful. regardless, you have given her an excellent start, you should be proud of yourself. best of luck, D.
