I had to double-check the number of weeks old Dio is...I'm starting to count in months now. So what's new? He's discovered his hands and is always chomping on his fingers or thumb. And when he's not slobbering over his fingers or twisting his hands together, he's (trying to) play with toys. He can roll over now, too.
He's been sleeping more fitfully at night again. I get a 3-4 hour stretch when I first put him down, then it's every 1 1/2 to 2 hours the rest of the night. It's been too hot to swaddle him well, and I don't know if that's one of the reasons. Dio is so sensitive to sounds and movement. I should try putting him back in his crib (which is right next to our bed) at night but I'm too tired to do anything but nurse him and go back to sleep.
Zari is having lots of fun with him, but Dio isn't so sure about her at times. She sometimes likes to play a bit rough. As in deliberately kicking and hitting him to see what I'll do. But she can also get him to laugh and smile. I figure soon enough he'll be able to dish it back to her.
