Guess who is who?!
Which one is Katelyn and which one is Ella?

Ella now is 6 months old

Ella- 6 month
Head: 16 1/4 in
Weight:14 pounds
Height:25in
1. Ella now knows how to roll over very well. Good job! Ella!
2. Ella can grab the toys and put in her mouth. Still drooling a lot.
3. Super under weight. Compared to 4 month(13 pounds 8 oz), She only gains 6 oz, which is one bottle of milk. I do not understand why her weight grows so slow. Other than weight, she is doing good.
4. She begins to eat solid food from 4 month and now she is doing pretty good now. In the beginning she keep pushing the food out by her tongue. Now she learns how to swallow. The doctor recommends us to feed her more solid to help her gain weight.
5. She now how to play her car seat toy.
6. She likes us to read books for her.
7. She likes to go out to see the new things.
8. She likes to talk a lot, and sometimes yells.
Overall, Ella is doing great. I love you! Ella!
