I found that the passage of time and a small fortune in booze made such issues largely disappear.
By the by if you think the smell is bad now just wait until they get to teenage years. There’s a funk that emanates from my son’s bedroom that would probably alarm UN weapons inspectors. My daughter is little better, she’s going through a weird phase where she’s aiming for a personal best for days spent without bathing. She thinks it hilarious. Pity the weather has turned cool, I’ve been wanting to try the spray nozzle on the garden hose.
