clothes for baby leaving hospital

Sophie 🌺

So I have only had winter babies (Nov and jan) so this time im due the end of May so it will be alot warmer when we leave this time (we live in South Dakota) I'm wondering if I should pack a t-shirt onsie with shorts or keep him in long pants?! this may be a stupid question but this is new to me as it was snowing the last 2 times I've left the hospital so it was a no brainer on what to put them In!
