be honest or blatantly lie?

[bananacarnival]

I've become good friends with a former colleague who lives near by. Her son is of similar age to my son +daughter. They've had a few playdates together, 3 is awkward but it's been ok. Except for the last time. Her son was very heavy handed -supposedly play fighting but lots of pushing ( also a heavy slightly overweight child) with mine, and consequently my son refuses further play.

The mum, whose friendship I don't want to lose, is often asking if she can come over as her son is still very excited about my 2.

Would you be frank and tell the truth or lie to spare her feelings? She's been very good to me through a difficult time and is already sad about the fact that her son struggles to make friends.

Thank you for any advice

I would be honest . That way she can speak to her son and help him understand what's acceptable

Is there a playground or duck pond you could meet at? Less for the kids to fall out about and you can take some coffee/tea in a flask so you still get to chat over a drink.
Sympathy- I've got a platdate tmw with new friends, which always makes me a little nervous.

Many thanks to you both, think honesty is the way forward
