Differences

Today Trisha is exactly 2 months old! I haven't been able to get her to laugh since the 13th. She still smiles a ton, though. I took her and Ty to their 3 year and 2 month check ups. Trisha weighs 8lbs and is 21in long. Tyler is 25lbs and is 35in tall. Ty still isn't on the charts and Trisha is in the 5th percentile for weight and 10th for height. Trisha really isn't very chubby, but she seems a lot chunkier than Ty was. And Ty didn't weight 8lbs until he was 3 months old. Trisha got 3 shots and she seems way fussier than usual. Is this a normal reaction?
Today is also supposed to be my cleaning and laundry day. I have done a little of both, but mostly wasted my day doing stuff on the internet. I feel bad because I can tell Ty is bored. Every time we make eye contact he says, "Mom, are you ready to go to Sadie's house" to which I reply, "We are not going to Sadie's house today" and have to continue adding extra things like, "At all" and "I promise!" because he asks so many times! So I guess I had better try to think of something to entertain him with.
