Baby Bea, welcome to the world and congratulations OP.
My son was born at 26+3 and he started school in Sept. It was a huge milestone as I remember the dark times in nicu where time & thinking is all you can do. Nicu is hard on the emotions and I am hoping you have some good support around you.
My advice, like others have said, is be kind to yourself. If people offer to help, take it. Let them cook a proper meal for you, help you out with bits at home - it will help.
Take pictures, Invest in a decent hand cream, stay away from goggle & take time to speak to other parents in the nicu.
Some of my closest friends now are people I met 5 years ago, we bonded over the breast pumps ☺ We laughed, cried and looked out for each other. When you take Bea home & the safety blanket of nicu is no longer there, it's invaluable to have someone to talk things through with who truly gets it.
I'm wishing you and Bea an uneventful journey through Nicu and sending you an unmumsnetty hug.
