I showered every day from birth with both boys, when DS1 was little I'd put him in the bouncy seat so he could see me, as he got older I either showered when he napped, before DH went to work or with him. By the time DS2 was born he would happily watch a Spot episode on TV, which then became Wiggles & Thomas, & DS2 would watch with him. When DS2 was 1yo I was even able to let them go on the deck (gated off & safe) while I showered with only one miss hap. DS2 got sort of stuck in the little car we had, had to jump out & go out on the deck with a towel rapped around me. I've always been quick at having a shower ( 3min showers a legacy of small water tank as grew up) & so would always be done in around 5mins & they just got used to it.
