Laura wasn't particularly adept at how to treat children, but she treated them about the same way she treated Rachel. Although she wasn't holding them. She'd put Rachel down so they could play together, and that seemed to suit them just fine. For the most part she'd only been observing to make sure that they didn't get all crazy and accidentally hurt the infant, who was just now old enough to really experience the holiday. It might not have been her first, but she interacted more with her surroundings than when she'd been only a month with an elf hat on.
When her mother swept in, she allowed herself to be pulled into her arms and leaned into the hug, returning it with one of her own. "Merry Christmas," she repeated out of habit of saying it all day, but she meant it none-the-less. "They are having fun," she informed the woman. It wasn't that she wasn't having fun, but more so that she was watching over them and it didn't bother her to be left with them.
