My 3 year old is addicted to the ipad

So I messed up, I vowed to never let my youngest whom is 3 he obsessed with screens like her big brother was and is. But working full time and then being the only parent home in the evenings to do absolutely everything as my husband works evenings I was finding it impossible to get anything done such as dinner, house work etc. so I’d hand her the iPad just to give myself sometime to get stuff done. It started with 20 mins here and there to watch YouTube videos that were age appropriate then during a long flight she discovered games and not soon after figured out how to download games on her own. Now we’re at the point where she wants it 24/7 and me being overwhelmed as it is, giving her more time than I should be. I’ve noticed a drastic change in her behaviour, it likely isn’t all to do with the iPad but also her age as she is 3 years old but she throws more tantrums, shows little interest in her toys, talks back, gets frustrated easily etc. this week I’m going to try a week of no iPad, I’ll let her watch tv but I’m going to hide the iPad away. I’m terrified of the tantrums this is going to cause but hopeful that after a few days she will be over it and we can focus more on her toys and playing outside.
