I have 3 under 3, so it's always loud, and they just don't know how to play together well yet, it's just fighting and fire fighting atm
My LOs are always screaming, running and bickering....they are mental and drive me mental but I wouldn't change it
I love my two as a pack but there is a 7 year age gap between them. However I do find the house is very loud and chaotic when they are together versus having each of them alone. It can be overstimulating at times.
