I hate all of them except Tyrogue, Elekid, Magby, Smoochum, and Snorlax, because the rest of them serve no purpose to me. Pokemon that are already cute and weak enough to be available early on, like Pikachu, Clefairy, and Jigglypuff, don't need baby Pokemon.
And even among those, Tyrogue is the only one I really like.
The only bad thing about Baby Pokemon was their horrible coin flip mechanic back in the G/S days of the TCG. That and how hard it is for them to properly implement them in the TCG, lol (the most recent Baby Pokemon can't even evolve into the Basic form and these days we don't even get Baby Pokemon cards).
