Happy Birthday, Babies (1) - S5.E9

It's Michelle's 5th birthday. Michelle is afraid she's about to lose her status as "the baby of the family", because Becky is pregnant. Michelle thinks this status is what makes her special. As a result, even though she can't stop it, Michelle doesn't want to be 5 years old. As the family convinces Michelle that she's special to them no matter what, Jesse is having what he thinks are sympathy pains.
