Can't.breathe....

A • Living the dream. 5 year old boy, 4 year old girl, b/g twins on the way!! What a surprise!! Due in December!
I have to elongate my rib cage and midsection to be able to breathe! Anyone else? One baby is high and one baby is low, but my lungs feel like  they are being crushed! Currently 26+6. Anyone else?
