sorry this might be long.....I am new here and have a few questions. I am trying to EBF my 3 wk old with the help of nipple shields due to a poor latch. While at the hosp after my LO was born I had extreme blood loss and exhaustion so I couldn't even hold her or try to start breastfeeding until she was about 1 1/2 days old. So she recieved formula and I pumped when I got home and then she latched with the shields and has been ever since. I try to take them off and sometimes she will latch without it and sometimes she won't. Depends on the day and her mood I guess. So anyways back to my quesiton now that you have some background information.......at night time my lo has a period (i think its called the Purple period) where she cries and cries and spits out my nipple if I'm trying to feed her, but roots around like she's hungry, and so I try again and she spits it out and screams like she is in pain......last night I gave up after about 2 hours and my husband fed her some formula, which she took and drank about 2 oz of. She then calmed down and went to sleep. Most nights we don't supplement with formula but I was losing my mind last night so I caved. When I put her down on most nights when she does that, I still try to BF her and then sometimes she stops and falls asleep and sometimes she will give in and actually nurse. Again it just depends on her mood. She also sleeps very well, at least 5-6 hours most nights and then last night she slept about 8 hours without waking up for a feed. Most mornings she wakes up and nurses really well for about 15mins or so (she is a fast eater). But this morning she didn't want it again and spit it out and cried and then also spit up some of what I tried to nurse her with. I'm not sure what to do. She acts like she is rejecting my milk and I don't want that. I feel like a failure and also that my milk supply is going to be lost. I try to pump whenever she gets fussy and won't nurse if my breasts are engorged but I know that EP isn't good either for your supply to stay up either. I have had no supply issues so far, and the LC actually told me I may need to reduce my supply in the beginning because I had so much. I also have a fast let down and sometimes she chokes on the breastmilk. So my question is, is this normal? I don't see spots on her or me that would indicate Thrush. And I also want to know if having her sleep through the night and mostly nurse during the day, will that make my milk supply decrease since I go so long during some nights? I'm just so worried that I'm doing something wrong and I really really want this breastfeeding thing to work out. So far it has, but these past 2 days feel like she is rejecting it. Thanks for any help anybody can offer, and sorry this was so long of a post.
