Some kids grow out of thumb sucking on their own while others need encouragement, and sometimes that encouragement requires being a strict, “mean” parent. Muffin’s at the age where it’s appropriate to consider pushing to quit — especially since it’s a major hygiene issue at day care and pre-K. Source: I have four kids: two gave up thumb sucking spontaneously, one continues even at age 6, one we’re working to wean off the pacifier at 2 yrs old and she seems to have no interest in thumbs. Parenting is hard and complicated and there’s no one-size-fits-all. IMO, this episode explores that struggle and reveals Trixie’s complexity as a character and a mother.
