single jogger question

2u2wow

anyone have the Valco single jogger?

i have the Valco and wasn't planning on getting a double as there's a toddler attachment  that clips on the front - but i'm thinking it may not work with a infant bucket carseat in there as well. and the store told me always remember to take the toddler out first or else it'll be so top heavy he'll go flying forward!!! WHAT?! i'm going to be a new mom of 2 u 2 and you expect me to remember this everytime or he'll go face first into traffic or concrete!? 

i'm just wondering what anyone else did - or any stories.

thanks!
