Is this cheeky to ask?

My neighbour who I’ve been speaking to for a month now has kindly said if I ever needed any help at all with childcare then let her know, she doesn’t mind at all. Now I am thinking of asking her if she’d like to take my little one on Saturday just for a trial and see how they both get on? Then I will ask her to help me out in a months’ time due to shift changes to take my son to and from nursery temporarily. I would never take the piss at all and I will offer fuel and her time looking after him. If you was said neighbour would you say I’m pushing it a bit?
