Hello
I BF my son until I found out I was pg with this baby. He was 15 months, although I hadnt intended to BF for that long originally. I am planning on BFing again with this baby.
My advice to you would just to be open minded about feeding. I was determined that I would be expressing & OH would be sharing the nightfeeds, but when it came to it, I found it easier to do it myself - sterilising, expressing etc are all such a hassle & I couldn't be faffed. Also I'm a bit of a control freak so if OH had done nightfeeds I would just have layn awake next to him checking up!!
The problem with expressing straight away is that it will mess up your milk supply - in the first few weeks your milk supply is getting established so you make the right amount for your LO. Expressing can mess this up. Also if you give baby a bottle in the early days it can cause problems with them latching on.
Personally, BFing was perfect for me. FF seems like a lot of hard work & expensive. Also it helped me lose my baby weight very quickly. It is convenient, i found it such hard work getting out of the house with a LO & all the stuff you have to take that if I had to take bottles too then I probably would never have left the house. Plus, as we are all told by the lovely NHS, breast is best health-wise for you and your baby. Also I had one period in the 15 months between having no1 & getting pg with no2, woohoo! And not to mention how much I loved it, it was such a wonderful opportunity to have cuddles with my beautiful boy! One of the things that people do complain about is growth spurts where you might be feeding for large portions of the day but honestly, looking back I don't know why I didn't just sit back, put my feet up & enjoy the time being forced to do nothing! This is the thing that I am most worried about this time as it will be hard with having my son also. I was very lucky with BFing, my son latched on & fed well from day 1. This isn't always the case & may not be for you, but it could be - don't be told how hard BFing is because it isn't for everyone.
So, I'd really say the most important thing is to be open minded & if you need help, ask for help - that is what midwives are for.
Good luck with whatever you decide!
