My toddler has been up since 6.15am (she does not nap anymore). She has just fallen asleep (4.45pm) as she is exhausted. she normally goes to bed at 7.30pm. Should I just put her to bed? She has not had any dinner, or should I let her sleep and wake her up at dinner time (6pm) and just hope she goes to bed at 7.30pm. Any advice please!!
