Choosing between 2 carriers

[springbride]

 

Ok mama's,

I'm back to pick through your wise brains! :)

DD is 18 mo, DS is due in June.

I have a maya ring sling, oh snap, mei tie, and a storch.  

I'm stuck between either getting a gemini (can you use this at the same time as an oh snap?) or a gauze wrap.

I know DD won't be willing to not be held once her brother comes, and we live in a hot climate (May-August 100* is a 'cool day')

Which one seems like a better fit?   I would buy them both, but DH just isn't going for that.  

ETA:  I'm trying to set myself up to have a couple of combinations of how I can wear both kids at the same time.  Our family lives 2 days drive away, so we won't have a lot of help aside from the 1 week visits here and there.

Congratulations!
I love my Gemini but I think you would be better off with the gauze wrap. Are you looking at a Gypsy Mama wrap? They are really supportive and really cool. I'm thinking it might be hard to get all the adjusting with buckles and stuff done if you have two ssc's on at the same time, it sounds like it might be uncomfortable. I think you could put the wrap on and then the Oh Snap and it would be more comfortable for you.
Good luck, it sounds challenging!
