Buster Milder

Buster Milder is the infant son of Ann Marie and her husband Charlie. He appeared on Bear's Adventures beginning in 1975 and continued to appear on occasion as late as 2002.
Ann Marie announced that she was expecting a baby in a letter to Maria in Episode 279, and subsequently that he had been born in another letter in Episode 1021. Several episodes followed in which Mister F and Miss I prepared for Buster's Arrival, who was finally introduced in January 1976.
The presence of Buster was a cause of occasional conflict with Mister F, who often felt jealous of the baby and the attention he received, as seen in Episode 1037 and 1040. One of Buster's most notable appearances on Bear's Adventures came in a scene where he was breastfed by his mother, who explained the action to Mister B.
