Breastfeeding each kid is different, especially going from one preemie straight out of the NICU to a preemie who went straight home. (34 weeks vs 36)
With my daughter (34weeker) it was really challenging. She was my first kid and I thought it’d be easier. They tried to help me out in the NICU but would only allow me to try to latch her for 5 minutes. This was frustrating for both of us as she was soo little and my nipple didn’t exactly fit in her mouth. I felt that they were very pushy and impatient with both of us. Some nurses were encouraging but others were very rude. Once we got home I kept trying. I was determined to be able to bf. About 3 weeks in baby girl finally got it. And I was soo proud. After trying and trying she finally was latching, it was good latch, and was actually drinking the milk. Going to lactation experts outside of the hospital really helped. A local nonprofit called MilkWorks was my choice and they were a blessing. The only struggle now, was oversupply. Baby girl was choking on my supply and letdowns. It took another couple weeks for her to get used to my supply and anticipate my letdowns. But we got there and I was able to breastfeed and pump for over a year. I only stopped because I got pregnant with my second and the cramping was BAD.
With my second a boy (36 weeker) it didn’t take him soo long to learn to latch. He got it down before we ever left the hospital. But my supply issues were instant. Even with colostrum. The supply was more than with my first. He was choking a lot and it scared me. Lactation assured me that it would get better and he would get used to it like with his sister. We are now 8 weeks in and he’s doing great. So what was so different with this time? Baby boy wasn’t gaining weight at first despite eating a ton. At a week old he was taking 3-5 oz a session and then randomly skipping feeds. The dr and I were confused at first due to the amounts. He said baby boy was just full and to give him more time to gain the weight. Lactation agreed and we did weighted feeds to make sure he was getting the same amount by breast. He was. At our next appointment baby boy did make weight plus some. He had gained several pounds.
All in all get help and ask questions when you need. There are people who can and will help. Lactation and your pediatrician are amazing resources.
You got this mama.
my son was in the nicu for over a month. Some are pretty forceful but others explained nicely that they just want to get our littles to build strong mouth, cheeks. It was challenging forsure! I’m so glad you seemed lactation consult outside of the hospital & your babies are thriving, you’re strong!! It’s not easy.
