Education is key, read a lot about it before baby arrives. I paid for a lactation consultant as my mum had warned me about how hard she found it and she had had a wonderful midwife help her. Midwives these days don't have the knowledge or capacity to help you the same way they used to. Best money i ever spent.
My DH was very helpful but I had to get him on board with it. He understood why breastfeeding would be best for our baby and was convinced to do everything needed for it.
He did almost all nappy changes (I changed 2 nappies in the first week!).
He brought me water and food.
He would take baby to another room with him so I can sleep and would bring baby to me to feed only.
He would help me with pillows to help me position baby in the rugby hold.
He did lots of the rocking and holding.
It looks like a lot written down but in reality being the only source of food for a tiny human is incredibly hard. My milk only came in on day 6 which meant he cluster feed until then!!! I was hallucinating from the sleep deprivation.
And it only got harder at the 3-4 month mark when the baby stopped sleeping more than 90 minutes at a time. I never got a break.
But at 5/6 months it got soooo much easier. Baby is 7 months and I'm so glad I persevered.
