Our little one 27 months all of a sudden started wanting us to sit beside her until she falls asleep. It happened a few times and she would sleep the whole night. Yesterday she kept waking up asking us to sit again and that went on from 3 to 6am until we were up for daycare. We are trying to do the chair technique but the waking in the middle of the night is challenging. Anyone has used a toddler light and how was the experience?
