Hey @loopylea I’ve got 2 young daughters (3 and 5) and before chemo I was so scared that I wouldn’t be able to do things that we normally do because I’m out and about everyday! When I had my initial appointment with the oncologist and doctor, they said it’s about your mental health aswell as keeping healthy pshysically, the advice they gave me was do what you normally would but with more caution and don’t be in very close contact ie hugging/kissing somebody with a cold/cough etc (pretty hard when you have a 3 year old that literally sneezes into your eyeballs 
).
I’ve carried on going to playgroups a few times a week but just steer clear of any extra snotty kids 
although hard when it’s usually mine! Extra snitiser/hand washing/not eating toast of shared plates etc! I’ve been to soft play a few times and done lots of kids days out and I’ve been fine! I did go and cuddle baby lambs on Easter and had abit of a panic and rang the hotline but they just told me what to look out for and ring, luckily I was fine! I’ve really focused on eating really well to hopefully keep my immune system up as much as it can be on chemo!
My daughters sports day falls in my low blood count time of my last one and I’ll definitely go but just again steer clear or any poorly children, it’s outdoors so I feel like it’s fairly safe. I was talking to my BCN the other day about this and I was saying I’ve managed to do everything I normally would apart from swimming during chemo and been fine and she said she had been talking to a lady who had pretty much stayed in the whole time, wouldn’t see family etc was pretty much isolating but she had still caught some pretty bad bugs!
All that being said do what you’re comfortable with, there really is no right and wrong 
On the eating front being on EC made me like that so I had to make sure I had a constantly flow of healthy snacks to eat what chemo regime are you on xxxxxx
