Thank you for your message. I suggest the following with large openings plug for you and small child.

Boreal Design Baltic - http://borealdesign.com/kayaks/baltique/?lang=fr

Baltic can accommodate tall paddlers and offers leg and knee room, promoting blood circulation

Riot Kayaks - Bayside 12 - http://www.riotkayaks.com/index.php/bayside-12

This kayak is a size and a half offers a spacious open feel for beginners, and for familiar paddlers, it gives you the flexibility to know what or who to carry: cooler, dog or kid.

I hope that answers your question.

THANKS
