April Cassandra Miller is a recurring character in Stuck With the Millers. She is the Miller siblings' grandmother and Todd's mother.
April is the grandmother of the Miller siblings and Todd's somewhat overprotective mother. She is very much like both Varian and Cassandra, but also can be somewhat mean and judgmental. She is also very overprotective and tends to take over everything when she visits the Miller home, to the Miller siblings' dismay. When Robert came out to her, she was very judging at first, but she eventually got used to it and now supports all her grandchildren no matter what...except if they break the rules. She is also insanely brave - often accepting weird challenges when she was young and being up to trying new things. She is very talented in a lot of stuff and loves taking risks, despite being nearly 80.
April is a smart, determined go-getter who isn't afraid of getting dirty...sometimes. Despite being a bit snobby and high-maintenance, she is very kind and generous and expects her grandkids to be the same. She is very straight-forward, honest, and not really too subtle and sneaky. She often doesn't understand the daily routines of the Miller family, but loves and supports her family a lot. Though she used to be strict with Todd when he was a child, April has gone more easy on him over the years.
