If we don't go out, my girl will start getting sleepy from 8-9pm. Then, we wake her up to have the last bottle of milk at 12:00 -1:00am just before we sleep. Usually she only drinks 3-4oz (Probaby too sleepy!!) She wakes up pretty early. Around 6-7. Sometimes 5:30am... So, I am pretty exhausted during weekend. Sleep late and get up early!
