Isabelle has no issue going down for naps with minimal whining, but at night, it's a full-blown tantrum to get her to sleep. Agh. Gonna let her cry it out for a few minutes and see if she calms down. If not, I'll give her a bath. She doesn't eat again until 10 and I can NOT take another 90 minute tantrum.
