Hi Neil and Hello back from Pembrokeshire - welcome aboard!
Is your boat already wheel or tiller steered and you're considering converting it to wheel? If it's tiller steered, I might be tempted to leave it that way for a while, esp with very young kids, for two main reasons, firstly as others have said, fixed seating will take up a lot of space in such a small boat and probably more importantly, they'll all be sat in front of you where you can clearly see them.
Feel free to drop me a PM as I'm also in Pembrokeshire (Pembroke) and would be pleased to offer you some advice if you're new to this boating lark... [emoji16]
