what kind of support would you like? That’s what it distils down to.
you only mention your children’s grandparents but that’s one very narrow source of support. I understand, my parents are dead Actually I was nursing my mother through her terminal illness when I had toddler dc so she couldn’t be of practical assistance but I could moan at her a bit and she could be an ear, and she could tell me stories about my own childhood which is something I miss a lot. She never met her other two grandchildren. Anyway, the point is what type of support you’d like. And how to find it. You can get support from a partner if you have one, from siblings, extended family, from friends, acquaintances, neighbours. From volunteer and charitable organisations, local government organisations, from paid staff, Nannies childminders, babysitters, cleaners, dog walkers, sometimes from people you don’t even know.
For example - When I was a single parent of young toddler DC my 60 something neighbour used to mow my lawn when he did his. Unbidden, he was kind.
Friends - friends are absolutely the biggest support to most of us. We holiday with friends so someone’s always watching the kids. I babysit for a wide range of friends, always have - I’m trustworthy and I like kids. I babysit for them and then they do for me, and the kids are all used to hanging out together. We have good old fashioned sleepovers and we rock up to each others houses kids in tow and we all stay over, make food, play games, we share the load. I host regularly and my dc always have stacks of friends over - it’s much easier for me. Mine are a little older now so I come home from work regularly to find 10-12 pairs of shoes by the front door so I get advance warning of how many kids are in the house
Pay - a childminder you like who can babysit the odd evening. The teen from over the road who can come over for two hours after school so you can go for a run. Gym membership with a crèche. Playgroups. Mine have done brownies, cubs, ballet, gym, street dance, chess club, board games club, swimming, football, all sorts. I’ve volunteered at the groups but also they help to get the dcs skills and confidence up which in turn helps you. And you don’t have to be in charge of an activity for an hour or so which helps with headspace and so on. You’ll be able to leave your oldest at least at groups and classes now so you can explore options to help ease the load.
And let the other parent step up so you can go out for a nice long walk or a hot coffee
