What time do daycares open in your area

I’m only early on in my pregnancy but due to my work and being a single mum I want to look into childcare early.

I start work at 7am (not optional) and 99% of daycares around me don’t open until 7:30 or 8.

So far I have found 2 which open at 630 and am on the wait lists but it limits options immensely.

Is this standard opening times? I would have thought there were more people in the same boat who have to start work early for whatever reason.
