Needing advice

Rachel

The last week my 15 month old has been waking at the same time, 12:30-1:00, every night screaming and crying and it’s taken hours to get him back down. I know there’s a sleep regression at 12 months and 18 months so I’m wondering if his 12 month regression is hitting late or something else is going on. He has always slept through the night unless his teething or something like that. I’m loosing my mind 😭
