I'm due my first baby in August and am having difficulties with change mats. We've been given 2 change tables (we only need 1 obviously). One is a mamas and papas and the part that would house the change mat is 70.5cm X 45.5cm. The other us an idea sniglar and the dimensions are 68cm X 47cm. I can't find a change mat anywhere that fits either table. Even the IKEA ones are the wrong size for their own table! It seems ridiculous! Obviously I want the baby to be safe so not able to bump its head on the table itself if the change mat is too small or be in danger if the mat overlaps the edges. Has anyone got any advice or a solution to this conundrum? Perhaps I'm being thick about change mats are supposed to sit on a change table!
