👶🏼Bedding In Nursery ➰ Dust??

Francesca • I have a little boy age 3, Rueben! , 17months TTC, I finally got my ➕ on the 24th October 💫👶🏼
So I'm 23weeks ➰ 3 days, I'm planning on making a start on the nursery over the weekend and was wondering......
(as I can't remember how many weeks I was when I did my little boys nursery 4years ago, but I do know it was towards the end of pregnancy due to house move and working up until my due date) 
....... How many weeks you were when you did yours, and also when you put the bedding in the cot, I wondering if doing it so early is ok, or if leaving its better due to dust and stuff?
