My 3 (almost 4yo) is regressing and I can’t figure this out.

My 3yo will by turning 4 this October - she has always had a bit of an attitude (I often call her the Sass Master), but is generally the most affectionate, loving child I’ve ever met. She always wants to share with her people, she always wants hugs and kisses, she drops “I love you”s without prompting.The last few weeks have been literal Hell. Up to about three or four weeks ago, I saw her every single morning to bring her to daycare and I was the one to pick her up every single afternoon. Then overnight, she had to change daycares and I had to change shifts - she is now in a public daycare center as opposed to a private family daycare, I don’t see her most mornings and most nights I don’t get home until during or after dinner.Almost every night is an absolute meltdown for nearly an hour; hitting, screaming, throwing things - “you’re not nice!”, “you’re mean!”, the whole schtick. On weekends we go through it four or five times a day. We’ve tried letting her cry, talking it out, reasoning with her, and today it came to a head when she threw aaaaaall her markers and crayons across the apartment. Now they’re sitting at the bottom of our garbage bin, and I feel awful.I tried positive reinforcement last night - she had a really bad day yesterday so I picked up some popsicles that she loves, and I explained that “today wasn’t such a good day, but if tomorrow is a good day we can ALL have popsicles together!” She was pumped, she said she’d have a better day today and here we are - I slept in a bit (until 10am) today, and it is 11:20 as I type this; she is still in her room screaming and crying.What the fuck else am I supposed to do? I feel like this overnight flip has thrown her for a loop and she’s probably super overwhelmed, but how do we deal with it? We make a point to plan to do fun stuff and get her looking forward to it in advance, and then she behaves like miserable Satan-spawn all week. This has been the hardest few weeks of my life, and now I’m starting to worry that this may be something more along the lines of daddy’s mental issues manifesting themselves early, because that’s EXACTLY how I feel when I’m overwhelmed and it took me years to figure out how to cope.I know regression is normal, but what the fuck, man. via /r/Parenting https://ift.tt/2M7B07Z
