Hey OP, I am a FTM too and my daughter is now 19mo we are still breastfeeding now
When I was pregnant I wasn't much bothered, I was formula fed myself, I just thought I'd do my best and if I wanted to formula feed I would. Didn't much think about it, I was too focused on the birth.
I wasn't prepared for how much I would want to breastfeed her once she was here. We were lucky in that in terms of latch, everything was fine. Emotionally, it was a huge transition to be so tied to another person and so relied on. The first 3/4 months were incredibly hard for me emotionally. But despite often being told to give her formula I don't know, I felt passionately that I didn't want to.
Once we started weaning at 6 months, it slowly became easier and easier and easier. After 12 months it's been a breeze.
People do say breastfed babies wake more, but studies have show that breastfeeding parents actually get more sleep over all. I presume because they don't have to get up and go make up a bottle. I fed my baby to sleep every night for the first year of her life, now sometimes her dad cuddles her to sleep.
A lot of women actually give up breastfeeding before they are ready because they aren't given the proper support.
I can only give my own experience because we're all different, but I found it incredibly difficult for the first few months but now I am glad that we persevered, it has always brought a great deal of comfort to my daughter and has been an utter blessing when she has been poorly. I suppose I did it even though it was hard because I love her so much.
Next time I will definitely be trying to go to breastfeeding groups for more support, but my daughter was born during covid and the support just wasn't there. I think this would have made a big difference.
