Congratulations!
My rule no..1 is never give advice unless asked for it!
I tell new parents that it is my intention to never to say "in my day we did such-and-such, but that I am happy to give an opinion or advice when I am asked for it."
Saying this in the early days saves a lot of trouble, I find.
In extension of this, I try not just to do things, but to ask, "would you like me to do the washing-up? or change the baby? or whatever is applicable.
Or say, if you like I could do the hoovering, sort the washing etc.
When her maternity leave is near its end, discuss with her what routine she would like you to keep to when you are looking after the little one, and try to keep to it.
It doesn't sound to me as if you will have any difficulties, but that may of course depend on what books on raising babies your daughter has been reading.
I had to bite my tongue very hard not to comment on keeping a child in nappies until he was nearly three and a half!
