My buddy's wife is holding the baby and she would reach up at shining chains or ear rings.
My buddy's wife would gently flick the baby's hand with her finger. Nothing to hurt the baby, just a little discomfort.
A few times of doing it and the baby would stop.
(Lesson learned)
Stuff liked that continued throughout their childrens lives.
They never waited to start discipline.
So true. That is real love and parenting.
