I have 4 DC and they were all EBF. DS1 stopped at 5 months, DD stopped aged 18 months, DS2 stopped at 19 months and DS3 stopped last month (aged 3). DS1 had formula but I didn't use it with the others. They all drank cows milk from 1st birthday.
I could write a book on my BF experiences, and those of mums around me. (I come into contact with a lot of pregnant ladies and new mums through my job).
I had a plan like yours. I also received the same reaction! In my instance, she was absolutely right.
What I will tell you is this. All babies are different. Some settle and sleep. Some don't. It's not something you can predict. My last one slept ON me for over six months (I was more relaxed). You just have to suck it and see.
For me, BF was the easiest solution. It's so easy, no prep, always ready to go. However, it does mean that you can't share feeds. It does mean that you can feed and then hand the baby over to DH to take for a walk while you sleep.
It does initially hurt (in a toe curling way) for the first few weeks and it takes a while to get the hang of it. (DS2 took a MONTH! The others, it took us about the two week mark, although I don't remember exactly). Babies lose weight in their first week. If I remember rightly, up to 10% is normal. Don't panic about this.
I used lanolin to prevent cracked nipples. I slathered it on. It worked wonders for me.
I had to express to get my milk flow started as one boob wasn't producing much. I had to do this with each baby (same boob!) and it took about a week. Electronic pumps are wonderful things.
Breast milk can be frozen. I also stored some in syringes for eye/ear infections. It really is magic stuff.
In the beginning, I would syringe expressed breast milk into my baby. I was told not to give the bottle and the breast as both required different reflexes and it could be confusing for the baby. So the nurse taught me to syringe very slowly, whilst using my little finger (in the position on the photo) to gently stroke and stimulate the roof of the baby's mouth. Apparently this is the same reflex as feeding from a nipple rather than a teat. It worked wonders for me.
As I said before DS2 took a month to fully establish. He was the hardest and I really had to work. But we did manage, and it was worth it.
I would say, on average, I spent the first six weeks feeling like a milking station. Supply/hormones/learning about what the baby needed, night being day and day being night... it was crazy. But after the first six weeks, things started to settle down into a routine.
Google 'the newborn Ten Commandments'. It's wonderful and spot on.
I hope you don't mind me writing an essay sharing all this (extra) information. Happy to chat by PM if you need. Enjoy the last bit of your pregnancy!
