Hi, Aya,
I must start with "ranting" and telling you that it is not a type of stroller that is comfortable from birth till 4 years. Imagine - this is a stroller that is THE SMALLEST THERE IS, meant for occasional use and travel, not for everyday multi-hour use. You need to be ready for it to be small = small wheels BAD on terrain, small seat - narrow for a 4yo, and often short (like the Yoyo, super slanted and very short backrest), rattly, getting loose with a lot of use.
You need to look at more expensive, better-quality strollers with taller backrests and sturdier frames. I have to say I would NOT recommend an ultra-compact cabin-sized stroller as the only stroller from birth at all. But if you really need one, go for a reversible Recaro Lexa Elite if you're a first-time parent. It won't last till 4 years I think, but it will be practical in the first years. Also, check the Joolz Aer, it has a bassinet option.
I personally would however strongly advice going for something more substantial for a small baby from birth, even at the price of it not being a cabin luggage-sized buggy.
