How to help my sister with first pregnancy / birth?

Hi all!

I am not pregnant but my sister is! She is 29 weeks at the moment.

When she goes into labour, I will be housesitting for her to look after her dogs so her husband can stay with her throughout.

What are some things I can do to help her for when she gets home?

I will do the usual vacuuming, mopping, I will make a couple of easy microwaveable meals for her too.

Just looking for ideas on what else I can do!

TIA 😀
