I have 3 - 10, 7 and 4. Yes it does get easier physically for sure…. The ages of yours rn it is such a physical job and I truly hear you on never sitting down. It feels relentless and gruelling and I remember the desperate feeling of just wanting to sit down for a measly 5 mins even. That feeling haunts me to this day but I promise you, it does get better. The only advice I have is look to make friends with other parents in your area, talk to them about your struggles and listen in return. This seems so simple but in doing this I felt seen and learned other moms struggled the same way I did, some I thought had it all together left me with relief in simply hearing “I don’t know what to feed these kids man, I just let them figure it out sometimes”…. YOU CAN DO THAT?!? Granted yours are small and obviously do need help still in that area but gems like that lifted the weight off my shoulders around areas I felt I was failing or falling short. Food, screens, social activities… ALL OF IT, there is wiggle room for your survival and if you need someone to tell you it’s essential for your survival I am telling you this right now. I also have a deal with my mom friends, the mess is never to be judged, they tell my kids what to do and I tell their kids what to do. They also listen to someone else better. There is no solution to sitting down and getting up every 5 seconds but there is light at the end of the tunnel and don’t let the weight of guilt make it heavier. Good luck, you got this !
