My DD was exactly the same. It’s exhausting isn’t it. It really does get easier though. Is it mainly in the evening? It can be normal cluster feeding, but it might be worth getting her checked for tongue tie - DD had a bad one which meant her latch was rubbish and she wasn’t getting milk effectively so all feeds were long.
I found it easier to deal with once I just accepted I was going to be stuck on the sofa for a while rather than checking the time and being impatient for the feed to end. Get organised before settling down for a feed, it won’t harm her to cry for a few minutes while you go the loo, get a glass of water, cuppa, snack, phone (and charger!) and the remote.
I can’t remember exactly when it got easier for us. There was an improvement after her tongue tie was snipped but it was quite a gradual thing. I just remember it being the hardest thing I’ve done at the time and then suddenly feeds were quick and I didn’t get a minute to sit down anymore! I then found I missed those long leisurely cuddles in front of a box set that I’d resented for the first few months. It’s easy for me to say at the other end of it, but try and enjoy the quiet time if you can.
Formula wise, although I definitely considered it in the hardest moments, I was desperate for breastfeeding to work out in the long term and personally felt, because of her rubbish latch and how hard I was finding it, if we started with bottles then we’d soon end up switching completely. I did start expressing the odd bottle for DH to give her from about 8 weeks once I felt breastfeeding was well established (was more hassle than it was worth looking back although good to know she would take a bottle so I could leave her with DH if needed) and began giving the odd bottle of formula from about 6 months ready for her starting nursery a few months later, she took it fine. I have no regrets about that as once we were over the worst of it I loved breastfeeding, it really did get so easy and so to me it was totally worth the hardship and I’d go through it again. Having said that, I’ll never know if we would have had the same outcome if I had given some formula in the earlier days and made things a bit easier for myself then. There are plenty people who successfully mix feed from the start or manage to EBF after supplementing with formula at first.
You should not feel any guilt at all for considering formula or giving it if that’s what you decide to do. You have to do what works for you. If you are wanting to EBF and are worried about jeopardising that with formula then it is possible to get through the hardest bits without giving it. But there is not ‘right’ way to do things and if formula helps you through then no harm done.
I’d recommend a local breastfeeding group for support if you can get to one. I rang the National breastfeeding helpline one night too. The lady I spoke to was lovely and I felt much better after talking to her.
It sounds like you’re doing a fab job, and congratulations on your new baby. 2 weeks was about the worst time for me from what I remember. 17 months in and I still BF at bedtime and any night wakings because we both love it and it works for us. My DD is no different to her little friends who were mix fed or formula fed from the start though. Good luck!
