Summer boy coming home outfit

Can I see what you brought your boys home in?

The outfit I chose has long sleeves and pants, my mom is making me second guess it because she thinks it'll be too hot. My MIL is making me second guess it because she doesn't find it cute. And ugh. Boys just don't have many things cute enough that's summer time for him to come home in. So when I saw this outfit I loved it. It could be around 60-80 degrees when we do take him home but even if it is hot it's not like we will be outside for long since we will be going from the hospital to an air conditioned car, to an air conditioned house that's like 10 minutes away. Thoughts?
