I need some tips for my sanity šŸ˜¬

3.5yo is ALWAYS touching the baby (1 month old so getting more into fussy stage). I get that he loves her and heā€™s a very physical person in all aspects of life but itā€™s making me crazy - mostly because he keeps doing whatever to her until she cries. I donā€™t like how much Iā€™m yelling at him but the listening is nil and natural consequences (sheā€™s crying loudly, I canā€™t do something for/with him because he made her upset, etc) arenā€™t helping.

I donā€™t want to punish him but not sure how to motivate him to leave her alone at least some of the time?? My first wasnā€™t so touchy so this is new to me. Thank you for any ideas! I think this week has been extra bad because itā€™s been rainy and he has pent up energy.
