Just as the title says really. Recently had DS2 and DS1 just turned 2. Very independent, laid back little lad, capable of going up and down the stairs himself, he can close a safety gate but cannot open one.
I know not one size fits all, so this isn't really an age question, more when do you know they are ready? I'm spending a lot of time breastfeeding and changing a million nappies at the moment and DS1 just wants to do his own thing. We let him play independently in the garden currently, flat grass all fenced in. But I've been reluctant to let him go upstairs and play! He always wants to be up there. What age did you let your toddlers ? How did you know they would be okay? As ridiculous as that sounds! We have a gate on his room so I can lock him in, but that restricts his movements round the house so a little hesitant. Would yous keep closing the gate or let him free roam?
