Wifey and I brought our darling to a friend’s house. As soon as she was laid down on the rocker with an overhanging thingie with suspended swinging toys, her eyes were trained on them and she swung her arms at them.
We hadn’t noticed this skill development because it never occurred to us to attach our own overhanging thingie onto our girl’s rocker.
We will only learn more when we learn from others. It follows that we probably should send our girl to childcare the soonest she is of age.
