This is storm baby.
Have you noticed that when an older child gets a younger sibling that they regress a little bit? Libby seems to have done so a lot. She doesn’t talk about it, but she shows us in many ways that she is still the baby. Else she really just loved this jumper that much, and that is possible! Maybe it is both.
She however didn’t love the thing so much when she couldn’t get out and when she yelled for help Mommy went to get the camera rather than getting her out right away. Pleased with me can you tell? LOL She is adorable, even when gloomy and annoyed!
