LO (8.5 months) used to be so good at entertaining herself for at least 20-30 minutes, but recently it's impossible for her to play alone in the floor, in the jumperoo, etc. It's exhausting to listen to her whine, and I would really like to get some things done even while she's awake. How can I help her learn how to do this? Will I have to just wait until she does it on her own?
