I feel your pain op ! It's very hard going from no baby to first one and the lack of sleep is hard, very hard.
Things that helped us!
Make use of dh baby just wants be be held to hand it over when you can. I second the dummy idea. I was dead against dummy's then I had ds and within a week he had one! No nipple confusion.
Skin to skin especially if baby is distressed, sleep with baby in your bed next to you, feed, feed, feed. Eventually they fill up, I promise!
There are no such thing as bad habits for baby's of this age! Do whatever you can to get sleep. If possible get food made by family and friends. Visitors must bring food and do a job in the house
Sod the housework and sleep!
It gets a lot better I promise you. Dd slept through from 8 weeks.
Take each day as it comes. Some will be harder than other, some will be lovely (and you'll worry something is wrong
).
Look at kellymom website for growth spurts and look at wonder weeks for fussy times. I found it helpful to get through those tough times to know it was just a phase.
Everything is just a phase, everything passes! Congratulations op now rest, snooze and sleep at every opportunity!
