Morning. First off, congrats!!
I’m a provider and my suggestion would be to consider a nanny. With those hours and days, a nanny or a babysitter is probably going to be your best option.
Daycare centres can take awhile to get in to (but definitely call around and ask to be put on the list!) and because home daycares are limited to ratios, many of us don’t/can’t accept part time/casual clients due to financial reasons so a home daycare may be impossible to find (but could happen!) There are listings ok eBrandon and FB for home daycares
Good luck!
