We bought the McLaren when our daughter was 7 months old, despite having a perfectly good Graco pram. The McLaren is awesome, she's now just over 2 and we still use it. We've been hard on it, and it's really lasting very well. If folds up into a really compact, light, stroller. Would definitely buy the same again.
Definitely the McClaren - it is tiny once folded up... and has a shoulder strap so great to carry around should they want to walk...
We actually got the Phil and Ted double stroller, for times that both my two (4years and 19months) need to go into the pram at the same time... Its alot bigger but very handy indeed... and great for exercising too.
