Как уложить старшего ребенка спать, когда так грустно от его взросления? Советы мам

I need to get my older kids in bed because of school tomorrow but i just don't have it in me to put her down. She doesn't fall asleep on me like she used to so these moments are becoming more rare. One day i rocked my older 3 babies to sleep and then one day i didnt do it ever again. Motherhood is so awesome but hurts so much sometimes. That pain of being so excoted watching them grow but longing for them to stay little forever 🥺
