My 3.5 year old has always been a live wire, but since the arrival of his sibling 8 weeks ago he has had a complete personality transplant. He is acting dangerously, doing things like walking out of the front door, touching things I've told him will hurt him or running into the road. When I try to talk to him or tell him off it's honestly like I don't exist and he's even had a 40 minute night terror incident.
I see the usual signs of new baby jealousy like toilet regression, baby talk and wanting to revisit breastfeeding, but these other behaviors seem severe. He can't even keep his attention of a book without getting distracted by playing or talking or making noise, and he used to love books, two or three a night and 3 months ago he'd listen intently most of the time.
Surely ADHD doesn't appear this fast and is the big change just a coincidence? My first born and I are inseparable, so feeding a newborn on demand and sharing my bed with her is a huge thing for him to accept from me.
Routine is unchanged for him and he's showered with love and affection. We've also brought books on the subject and prepared him best we can. He's included in the daily baby stuff as much as he wants too.
Had anyone been through it? Thanks in advance.
