Being from Texas, both of mine are of the thin blooded nature as well. It is funny hearing some people think 60s isn't cool and I have been wearing sweatshirts myself when taking my girls to school in the mornings
Monkey tolerates cooler weather better than Maddie. I like to sit outside when it is cool like this (in the 60s) and have a blanket to cover my legs. He will climb up and nest into the blanket and sit with me for hours. Maddie however insists on being in my arms and then covered up. I think she is looking for more of my body heat!
Good luck finding the right temp for your babies!
Peggy, Monkey & Maddie
