My advice would be

- DO NOT try to do everything, the housework isnt going to go anywhere, it can wait!
- Take a nap during the day if you can while bubs is asleep, it makes it easier when you are getting up for night feeds, you arent as tired
- If someone offers help, take it - if someone offers to hold bub while you do the housework, tell them to get stuffed get them to do the housework, you need to rest
- Go for a walk once a day, round your area, or in bad weather around the shops. You'd be surprised how much better you feel after some exercise, especially on the days where you've gotten very little sleep the night before
- If you need help ask. Ask your partner to do some extra chores for the first few weeks or months. Ask a friend to c0ome round & watch bub while you have a bath, etc
-Dont stress about being in your PJs all day & not having time to have a shower or clean your teeth LOL
- Do what you feel is right, you know whats best for you & your baby

And most important of all, You bub is only this young once. Enjoy every minute of it. Good & bad, its all part of the journey. And take lots of pictures, they grow so fast!

Good luck!
