Sleep training day 4 and some happy shopping

Today is day 4, I put her in her room at 9:15pm, she gave up crying at 9:24pm. It seems like she keeps crying about 10 minutes after left her room since yesterday. But she starts crying earlier everyday. Day 1 she started at least 3 minutes after I left. Day 2 and day 3 she cried right after I closed the door. Today she cried before I even left. I think that it's because she's getting to know what's going to happen next.
To confirm all these torture process is good for Sophia, I read the book "what to expect toddler years". It turned out I was doing everything right. So I don't feel much guilty while listening her crying without doing anything. All I added after reading the book was a kiss and telling her I'll see her tomorrow. Hope we get over this soon, hope I'm not pushing her too much.
There are some good changes of Sophia after I started sleep training. She eats better, more real food, less snacks. She sleeps less at daycare during the day, I hate to her report says she slept from 12 to 3, she doesn't need 3 hours nap. Hope these good changes help sleep training.
I did a little shopping today, which was very successful. Grocery shopping, got what we needed for the rest of the week and a pound of fresh strawberry. Sophia enjoys sweet strawberry very much and keeps asking more.
I aslo did some happy shopping at Barns and Noble, got some books and a Happy face weekly planner. The cover is very cheerful, the design is very functional, even has a pocket for me to store coupons and notes. Now I can downsize my wallet. Now I think I'll next year refill for full price (scary).

Mom: Are you happy, Sophia?
Sophia: Happy!

Sophia learned a new word "happy" with my happy face weekly planer!
