Hi mamas. I need seriously encouragement and help... currently sleep training method when you leave baby 3 minutes, 6 minutes, 10 minutes. Daughter is 18 months and is having an absolute melt down. Screaming Dadda and choking she's crying so much. Going in doesn't soothe her she's just desperate to be held. Help! Anyone done this? Am I doing the right thing? I have an baby on the way in April and really want to nail the sleeping thing.
