3 weeks and tummy time

Teresa had her 3 week doctor's appointment last Friday (instead of a 1 month appointment). She checked out as healthy as can be and growing well! She is a good eater just like her brother was. Here is how she checked out...
Weight: 9 lbs 4.8 ounces
Length: 19 1/2 inches (she is shrinking I guess!)

At the doctor's visit, we got the okay to start some tummy time. Timothy is very interested in every new baby item we pull out, so of course he wanted to "play" tummy time along with Teresa.
Teresa is doing well at trying to hold her head up. She doesn't seem to mind being on her tummy that much. The picture below is her first tummy time experience.
