I wouldn't worm anyone as routine... unless you had a reason! lol
We worm Charlotte as the need arises - so far twice. We have a cat, and DD likes to share food :rofl: But when we found her consistently complaining of "sticks in her bottom" and put together with mystery "my tummy hurts" 30 mins after any meal, we decided to worm her. Funnily enough, no more sore tummy, or nasty bottom sticks, since.
Is they are around lots of animals or something, then I would look it as a possibility for certain issues or complaints - just another thing to look at on your mummy list of ailments lol But otherwise, no, we don't do it as routine.
