List some hard facts for later references:

1. Hold the bottle by using two hands (Dad did shoot photos, and Mom did tape videos) drinking up the whole bottle. It was not much though, 100 ml.
2. Start to babble around 2 months, especially during the morning, she would look into your eyes, raise her eyebrows, and talk to you for long.  These few weeks, she seemed to babble less, maybe because her attention was consumed away by other activities, e.g., playing with objects.
3. Around 4 months, she started to play with toys; she can hold rattles, small books, other stuff, and play for long.
4. The record duration of not having a single stool was 5 days, which happened around 4 months. We were all paranoid, but instantly relieved when she ousted a record giant tool from her little body, on the evening of the fifth day. It should be normal for the baby who was exclusively breastfed.
5. I got her a high chair from Amazon. It was shipped in fast. She looked so cute sitting in it. Today we had dinner together, but the whole time, she was playing the Big Singing Worm.
6. Can sit without assistance up to 30 seconds.
7. She started to have rice cereal from 4 months. She seems to really enjoy it.
8. She started not liking to eat from my breast, except during the night. It made me a little bit sad.
