With two new little girls in the family, Andrew spends a lot of his time either watching the girls get fed, or watching Catherine pump breastmilk to feed the girls later. Not surprisingly, he doesn’t find anything abnormal about pumping himself. At first he needed Catherine to do the sound effects for him, but he has since learned how to do it on his own.
That is hilarious! My nephew would imitate pumping when he was little but never did the sound effects.
