DD suddenly refuses to nap! Just a few weeks ago she was able to just go to sleep while playing, then continue play after waking up, easy peasy. I know babies/kids change & adjust as they get older. Her night sleep is still fantastic, waking up only 1 to maybe 2 times a night & sleeping until at least 7 or 8. But now morning is the only happy part of our day. If I am able to get her to nap it's usually 30 minutes tops. & she is mildly grouchy after. I've tried rocking, swaddling, singing, holding her, wearing her, allowing to sleep on her stomach; nothing helps! I just want to help her feel rested & happy again! Any tips?
