I'm having a break down right now. My 16 month old daughter is sleeping over at her cousin's house tonight. This is the first time she's been away from me overnight. I feel like such a baby. 😭 I miss her so much already. She sleeps with me so I'm pretty sure I won't be able to rest tonight. I'm just so use to her being here with me. I know she's in good hands and having a blast though. I just love my mini me with all my heart. How old was your baby/babies when they had their first sleepover away from you?
