Wow you must be feeling very overwhelmed, particularly after what sounds like a traumatic birth and difficult first baby. Well done on managing breast feeding!
I just wanted to share that my sister and I are 18 months apart and have been best friends since I was born. I’m so glad to have a sibling so close in age.
My mum had a very difficult time with my elder sister - back to back labour, 3rd degree tear, forceps delivery. It should have been a c section and she had PTSD afterwards. To add to it, my sister was a very difficult baby - colicky, with an undiagnosed cows milk allergy (transferred through breast milk). She just didn’t sleep for the first 8 weeks! Mum gave up breast feeding after two weeks. She got much easier as a toddler.
Then I came along and was a dream baby! Slept through from the start, never cried. Practically perfect in every way 💁🏻♀️
My point is that a difficult first baby does not mean a tough second baby. It’ll be hard, but you’ll get through it! And at least it’s all over with in a few short years in stead of having to start over again just as your eldest is more self caring!
Look after yourself and make sure you ask for help from your real life support network - medical professionals and friends/family. Absolutely no shame in needing help - it takes a village to raise a child (and keep mothers of newborns sane!)
