Formation in situ from disks with radial mass surface density, $\\Sigma$, profiles similar to the minimum mass solar nebula (MMSN) but boosted in normalization by factors $\\gtrsim 10$ has been suggested. We propose that a more natural way to create these planets in the inner disk is formation sequentially from the inside-out via creation of successive gravitationally unstable rings fed from a continuous stream of small (~cm--m size) \"pebbles\", drifting inwards via gas drag.
