First of all, is your husband a complete moron that doesn't do anything with his own children, that he would say this to you?
Is he the reason your MH is poor?
What a really dumb response.
This is one of those situations where "momentary discomfort prevents long term frustration and resentment".
Have you their mobile numbers?
If you do text them a firm "absolutely not, I have enough on my plate with wfh and two children".
These people are 100% users.
Stand in front of your mirror and start practicing saying two things "that won't suit me" and "let me text you back about that".
These two things give you an out.
I was a sahm for 4 children and even though I am no pushover, I became very adept at brushing off the requests from nice friendly CF's.
It is hard to put into words what a complete PITA it is to be factoring in another childs transport.
I did it for a couple of weeks for a friend who was in hospital and it was a complete pain.
My children sometimes wanted to be in early or later for various reasons and it meant remembering to text the different time every other night.
Just more pressure on me.
I did it because it was a good friend.
Not a chance I would entertain it for a stranger.
This is only the beginning of it.
Dropping children to school is a pain, especially during the bad weather.
Absolutely no way would I get involved with such an enormous ask.
The sad truth is anyone I know who has ever done so said it was the most thankless, unappreciated favour that was difficult to offload.
Please stay strong and just say No to everything.
You will be saving yourself so much grief.
People who find it so easy to ask for huge favours are NEVER real friends.
These types are ALWAYS on the lookout for a pushover.
I have heard a top tip from one working mother to another pre starting primary school, "make friends with the sahp's".
It's a solid tip, but not if it is your phone number that is the one being used.
So many women work so in a class of 25+ children, you could easily be getting a favour from one or other every week.
I have had froends who lived near urban schools take to turning their phones off, such was the level of favour asking.
