We have a Pre-Schooler's trip each year where all children are under 5, many just babies. This is in the first week of May, next year it will be from Tuesday 3rd until Friday 7th May - this will be appearing in the calendar shortly. It's always a popular event (it's based on a farm), and a great way of getting to know parents with similar aged children.
I'm not sure which trips you've been on up to now but there are usually children of all ages on our events, from babies through to teens. If there are any trips you fancy but want to check out the ages beforehand, just drop Pauline an email at firstname.lastname@example.org
and she can let you know if any tots are booked.
