Hey ladies, does this happen to you too? My daughter takes f-o-r-e-v-e-r to get ready. It's insane. We live in a two-story house. I always go downstairs to the first floor to wash up, make breakfast, and get myself ready. Today, we had to go for an ultrasound. I woke up the older one, got the younger one ready, and took her to daycare. An hour passed from when she woke up. I went upstairs to check on her – and she was standing there in her nightgown, staring at her closet. AAAAHHH. I took her phone away. No movement. Silence. I yelled at her a couple of times to get dressed (I hate running up and down the stairs). Long story short, 50 minutes later, she came down for breakfast. Still in her PJs (meaning, still in her house clothes, she still needed to change). In that time, I managed to text a neighbor, post on social media, check the route to the clinic, pay the car insurance, and make breakfast. Seriously, it's a nightmare. Every time, getting ready takes 2-2.5 hours – and I'm constantly yelling that she needs to hurry up, move faster, we need to leave soon, etc. I don't know what else to do. I've scolded her, yelled, punished her, begged, explained, offered rewards. Nothing works. Should I stand over her the whole time? I wouldn't even have time to get myself ready and eat. She used to get ready quickly as a child. I don't know what went wrong or when. If she has her phone, she just stares at it blankly. If she doesn't have her phone, she might sit down and read a book. I have no idea what else she does in her room. I'm just at my wit's end (((
