Does anyone have a toddler?

My son is 4 and we haven't explained anything about the new baby yet because we feel its a little too early. But.. the last two day he has been uncommonly clingy which i dont mind at all :) but he has asked to sit in my lap the last two nights and i have rocked my big baby to sleep. Im loving the attention because he's been so "im a big boy mama" for the last longest im loving the extra cuddles but does anyone else have toddlers that seem to sense they arent the baby anymore? Lol idk what he's gonna think when the baby gets here 🤤😊
