Buy vs Lease for soon to be parents

Hoping for advice! My husband and I are expecting first time parents and are looking at upsizing from my Toyota Corolla.

I am looking at Compact SUV - specifically CRV and Tucson as they are largest in their class. This is due to my husband driving larger SUVs, and still living in the city (for a bit longer).

However, when I look ahead we may have another child in 3 years and want to change out of the car for something larger. My initial plan was to buy and keep until payoff in 5 years then re-evaluate upsizing again if needed (more kids). I could see being tempted to upsize before this, but generally I’m pretty good at sticking with a car - I’ve had mine for 12 years. Husband is very pro-lease in this scenario as I do not plan to keep the car long term.

Financial breakdown is below:
Lease
36 month 2,500 down - 448/month

Buy
5 year with 10,000 down at 3.9% - 548/month

What would you do in this scenario if money is there to make the purchase? I’m usually very against leasing but this scenario has me questioning.
