I think Carmela (being similar to Karina) needs lots of soothing time to get to a calmer sleep state. So if she doesn't get lots of calming, she'll talk for awhile (I think Karina was doing it for over an hour last night at bedtime, which is very odd for her at night!) Maybe you can try being with her in her dark bedroom for longer before putting her down. Might calm into a sleepier state.
