I need to vent and have someone empathise - about my babies?

Why can't they take the 4 year old for a walk? I bet he'd love to go for a walk. I do understand, that baby (babies) are mine (not your babies), they can do the older kids. Of course usually when there is a little one I'd like someone there to make food for me, take them when I need to use the restroom, clean the house - take over my usual stuff that is but that's it.
