Latest on Olivia

I know a little about developmental milestones for babies Olivia's age so when she does something new, which seems to be almost every day, I get excited. And thought I'd let you know what shes been up to this past week.
-she started pointing! just one morning rolled over and started pointing and hasn't stopped since.
-she started signing for "milk"; it does tend to be a sign she does for a lot of things too, but when she is having milk she does the sign and she understands when I do the sign
-she is putting things into things for example her egg rattles are going back into the mixing bowls now and then she hands them to me; she is also trying to stack her ring stack
-she loves to find things I hide in her shirt or under a blanket or under my pants leg and then hands it back to me to hide it again
-oh, and did I tell you she has started sitting up and standing up in her crib at night instead of sleeping? That has been an interesting occurrence for me, some nights way too many times. She tends to think it is funny.
I think there is one or two more I wanted to post here but can't recall at the moment. Here is a little video of her standing and signing at the same time.
