Learn to breastfeed lying down, and co-sleep! That saved my sanity and meant I started getting lots more sleep as I didn't have to physically get out of bed / sit up to feed the baby. I now just put the boob in his mouth when when he starts looking for the boob and he never fully wakes up / cries, and I usually doze off too. My DS is 4 months, and feeds several times in the night, but this way I get almost a full nights sleep and feel rested in the morning. My DH now sleeps through the night too (!)
Wash their bums in the sink when they've done a poo! A lot less faff than cleaning up a massive BF baby poo with wipes and getting poo all over your hands / the mat / your clothes / their feet etc. Also better for their skin!
When changing a wet nappy (for boys especially), put on a clean nappy underneath the current one (as though you are putting on two nappies for your baby), and then once you whip the old one off, you can do a quick wipe and the clean nappy is ready to be put on. It's also there as a quick shield to prevent getting a spray of wee in your face / hair / baby's face / the walls / the sheets / the floor.
Take a baby moon! We didn't have any visitors (except grandparents) for the first 2 weeks. If you have family close by, make full use of them. My mum came over during the day for the first 3 months, and it meant she could watch DS while I had a shower / ran out to the shops, and I felt a lot more normal and could enjoy the baby a lot more. And it was nice having some adult company too!
It's never too early to start reading books to your baby, but colourful board books are more sensible than elaborate stories. My DS at 4 months prefers his books to any of the toys he has. I would have never thought of getting him board books, and was suprised how fascinated he was by them at just a couple of months.
Enjoy this time! They grow so fast. My DS seems to be learning a new skill every day and I already can't remember the days then his tiny baby clothes were too big for him!
