My toddler has just turned 21 months and is struggling to sleep at night. Tonight I gave him his usual milk in his room, then had a quick cuddle, put him in his cot, turned off the light and left. The issue is that as soon as he realises I’m leaving, he starts to cry, stands up in his cot and shouts for mama and dada. Would you continue to leave the room at that point or go back in and comfort him? I’ve been out of the room for seven minutes now and he’s still crying. I genuinely don’t know how to deal with this - it’s been going on for a month now and I’m really struggling mentally! Any advice very welcome.
