I think they sense that big changes are coming to our household. They've been very clingy with me lately, following me from room to room. They're also really curious every time I go to the nursery, which is often. They'll sniff around and after a minute settle into a comfortable spot and just hang out with me in there.
We've started leaving the nursery door open so that in the mornings they can go lay in the sun. I hope they make the transition ok when the baby arrives. These 2 are my first kids, after all.
