I have stairgates & cupboard locks on my cleaning products, sharps & medicines in the kitchen otherwise nothing that I don't already have for my own dc (blind cord things, windows locks upstairs as we have big opening windows) . I shut the upstairs bathroom & our bedroom so childminding children know not to go in there.
My days is much like others: breakfast& arrivals at 8, school run, home to gather snacks/drinks & nappy change before heading out for the morning (toddler group, leisure centre activities, cm group soft play plus parks, woods, farms in the summer) or sometimes me & another cm get together in each other's homes for a structured activity we can use for an observation like baking or craft session. Home by midday for free play whilst I make lunch, naps, usually have stories on the sofa after naps then either something simple like play dough or colouring or more specific free play (I'll get out a train track or little people set etc). School run, home for snack or park in the summer and more of the same ie crafts - cutting & sticking for little ones, Hama beads or jewellery making for older ones, free play, games, sometimes a bit of TV, dancing (they all love this
) , older ones do homework.
Some leave at 5pm, tea with my dc at 5:30 and last ones go at 6pm. I have a quick clear up then see to my dc homework, bath etc before collapsing on the sofa. I do minimal housework as I go along ie quick Hoover & put a wash on in the morning, hang out washing & cook evening meal whilst lo's sleep but most of it is done on my day off or at the weekend. Paperwork I just ignore 99% of the time & have a massive catch-up in the holidays or if I know Ofsted are due
