I just feel completely lost. Is it really supposed to be like this?

Ma

Am I doing something wrong or is parenting/life with young children just this tough? I have a 5yo, 3yo, and almost 2yo. I’m a SAHM for the moment and I am counting down the seconds until I go back to work. I feel like every day (despite me waking up saying it’s a new day, having activities planned, and being positive) is just filled with bickering, crying, and arguing. For example today from 9-11 we were outside and all my children did was fight over the lawn mower and fight over dirt piles. It finally stopped because I took my youngest in and played with her in the basement while the older two were outside (I could see them from the window and we have a fence). Then they came in because it started raining and then all they was knock down each other blocks or argue over the tunnel. Then during my youngest nap time my older two argued over play doh pieces and then broke our brand new game from the Easter bunny. I’m here modeling, coaching, encouraging, natural consequences, teaching coping skills/manners, doing my best to keep cool (I’m not perfect but overall I stay calm) and I just feel like everything is a total mess and we literally can’t do anything without conflict. It’s so discouraging. Like I asked before- am I doing something wrong? Or is this just life with young kids?
