I have a 15mo ds. Tonight I'm out and my DH and his parents are taking care of ds. Just got messages saying he's been screaming and cowering in the corner from my DH like he was scared and really struggled to get to sleep. I usually do bedtime but do go out every few weeks but it's never been this bad. My DH is really upset and has said I need to fix it. I don't know what to do. Is this normal? Ds is generally clingy in the day but will happily be left at nursery 4 days a week.
