SAHM of 3+ kids: how much help a week do you get with babysitting?

Al

We have 9 and almost 7 year olds and a little guy who is almost 16 months. We are thinking about TTC for a 4th living child in the next few months. One of my biggest worries is making sure I’ll have enough help/support once we have another baby. Right now with COVID, I’m teaching both my oldest girls and watching my one year old almost all day (DH works). Our only source of help with the kiddos is from my mom, Mon-Thurs for 2 hours, (12-2pm) which I am SO grateful for but worried it may not be enough if we have another baby (plus I don’t know if she’d be willing to watch another baby, she’s almost 70).

So for those of you who have 3 or more kids, how much outside help are you getting a week? Another worry of mine is that DH and I hardly have any time to spend together. I guess hiring a babysitter for the weekends is an option but I’m not big on strangers watching my children, especially during COVID.
