Weaning

My LO usually breastfeeds for comfort especially for nap time and bedtime. When she’s fully weaned, is she going to still want to cuddle with me 😢

Also do babies ever still suck on the boob even when there’s no milk anymore (more like a pacifier?). I was always curious about that because my LO uses it as a pacifier. Or does she innately know that she should no longer suck on it since no more milk?
