They're all different and it varies so much, my first was not a fan of sleep and I was alone bar a partner that was rarely home and when he was he was more hindrance than help, and zero funds.
I threw all my expectations in the bin, if we got through a day in one piece we were golden. I had all these ideas about pushing a pram in the autumn sun with shiny hair and a cooing smiling baby. Reality was at some points, if I had a five minute shower every three days I was really winning!
Cover the basics, screw the rest. So, make sure you have eaten, and have food in for yourself, pay the bills on time. Sleep/rest when you can, which is the most infuriating advice ever! If you go beyond tired and into wired it can be hard to switch off, but closing your eyes and lying down with a meditation is a good second. Look into cribs that attach to the side of your bed.
There are supermums out there with babies that sleep that will be out there immaculately groomed ticking off baby sensory, baby swimming, baby trips to the zoo... hats off, I was not one of them! Don't pressure yourself to perform, be kind to yourself and you'll both be ok x
