Perfect.
What’s with the anime with the little batman picture
When my children were small, when they were on our laps we used to hold them by their hands and lower arm and alternate pushing the arms back and forth so their trunks would turn one way or another while singing NaNa NaNa NaNa NaNa NaNa NaNa NaNa NaNa and hang them backwards upsidedown as we then would cry BAT-BABIES!!!
Thank you Batman, for the memories.
