A question for those with the Quinny Zapp pushchair. - Has your LO discovered how to pull (or rather push) the rain hood off? And if so how long did it carry on for/how did you stop it?

DS who's nearly a year has taken to pushing up the raincover hood so it becomes unattached. We don't use it much as it's our 2nd pushchair but it's starting to drive me insane. Last week I spent my whole time round TK Maxx with one hand on the handle bar and 1 hand holding the hood into position so he didn't pull it out again. Driving me so mad I'm really considering selling it and we don't have that problem on his main one and I can't think how I can stop him.
