Just bathed dd who is 3.5. Leaving the bathroom for anything fills me with fear - you always hear the stories about 'but i was only gone for a second' However ds was screaming (11 months) so i had to run out to give him his bottle and put him into his chair.
I made dd sing 'twinkle twinkle' as loud as she could until i came back lol that way i could always hear her and if she stopped i could run!
What age do you start leaving them for a second but know they'll generally be ok?
