Worried about worms

[M2025]

My child 19 months has been with another child and they kept touching their bum so naturally I am worried that my kid may have picked up worms or something. Any advice so I don’t worry myself silly? Thanks

If it turns out that's the case then there easy treated from the chemist I wouldn't worry as you'll no right away if they get them and it's treated very fast and they'll goaway x
