Training my replacement for my mat leave, need advice!

So for the past month I have been training my replacement for my mat leave. Ill be gone for 12 months and we needed the extra help so she will be sticking around after my return - if I return 😂

The girl is nice definitely not my cup of tea but work is work, not looking for a best bud lol

She learns quite quickly and is doing good technically. But the issue is she seems lazy... she lets me do most of the work. She never just takes initiative and answer emails we get or try to help people who are emailing. She just leaves it until I answer it... when I ask her like “hey do you want to answer this email” she says “oh you can do it” or my personal favourite was “you must be bored at home why dont you do it”. I work remotely because of covid and pregnancy

Today, I was swamped with things and we get a very easy troubleshooting email and I ask if she can do it and she tells me she prefers not to cause that guy gave her attitude last week”.... so I was just like fine ill do it.....

Ive been at the company years... why is she telling me what to do... I just feel like when I started this job I was so keen and wanted to go above and beyond. But her... its seems like shes ok with letting me do everything.

Ugh just venting I guess. I just dont know how to tell her to get it together. Cause im gone in 2 months and if she doesn’t practice she wont know what to do when im gone!
