Made a very lovely mum friend, her son is so lovely and my 2yo and he get on so well. We go to playgroup together. It's only been a couple of weeks but we were all getting attached. They also live 1 street away so always see each other on walks.

She's told me they've "naturally immunised" him with homeopathic sugar pills that have the diseases/viruses in them but obviously... that's not a thing. We mostly play in the outdoor park together but I've also got my 4 month old with me, he's the most at risk here.

How do I let her know we can't go to playgroup anymore or have park playmates? I just need advice how best to write the message and what my plan should be. I won't be going to this playgroup anymore I think, but we'll probably bump into each other :(
