How do I ask my husband to hire a pro instead of DIY home repairs?

So me and my husband recently bought our first house. It's a nice place, but it needs some work and my husband has been trying to do it all him self. He's been doing ok, but he want's to install a ceiling fan over our bed. And I'm concerned. This would involve wiring because our bedroom doesn't have a ceiling light and it would involve making sure a fast spinning blade machine doesn't all on us when we are sleeping. He is not a handyman or an electrician he's a programmer. So I'm nervous. I've been trying to hint at getting someone else to do it, but he's been so stressed about being a new dad. Recently he's started focusing on getting the place ready for the baby so he's been a lot happier. So I don't want to crush him when he's starting to feel like him self, but I also don't want to be crushed by a fan that is also on fire.

So my husband installed the fan, or well he's installing it. I was just honest, I shared how happy I was about all the hard work he's been doing and I said I'm just concerned about it falling. So we called a family member who is an electrician we sent some pics and he gave the green light. I feel better, I'm still a little nervous, but that's normal for me I don't like construction lol.
