Cardigan for 3 year-old girl

I'm slow. Slow in doing anything, with sewing, crocheting, crafting, cooking. So when I saw the book Crochet in a Day for Baby (sample), my eyes shone. I may have a cardigan made on my baby's third birthday. The idea was so inviting.
My baby wanted a yellow cardigan for her. She liked the yellow dress Belle wearing in the movie "Beauty and the Beast," and she wanted the yellow cardigan to go with the yellow dress she has. Haizz, movies do affect a lot in life. My baby is not an exception.
I have to explain more about the yarn I used here. I stocked yarn. There was a time I kept going to Michael's to look for clearance yarn. I intended to make this and that dress for my baby, I downloaded and saved the patterns but most of them required light weight yarn. I found some Bernat Softee Baby yarns on clearance and grabbed them. But, they have been in my boxes for a long time. No time to work on those patterns any more.
Now, my baby is in preschool. I try to have more time for me. Drop my baby off at her school, stay in the car to crochet for a little time, then head to the library to study something. However, I have been spending more time on crocheting than studying. I am addicted.
Now, yellow yarn. I don't want to buy any more yarn. Digging in the boxes, I found 2 skeins of Bernat Softee yarn. They are 3- medium weight yarn, not the worsted one as required in the pattern. Sigh, I had to calculate the stitches. Luckily, I have another cardigan made by the same yarn but in the color of aqua. I got it out, counted the stitches and made some simple calculations. Done.
Smaller yarns cost me more time to complete this cardigan. The texture doesn't look the same with the one in the book but it's still fine. I may try another one in future. Love the colors the author Candi Jensen used.
