Does feeding solids to baby keep them full at all?

Its fine. Sometimes my boys would eat more than one jar of the stage 1 by that point but it takes time for them to not gag on the textured foods. My oldest son though gagged the longest and we discovered his tonsils were to close together and to large but usually it is just getting use to the textures. If you do a cereal in the morning and snack then a jar of food then a snack then a jar of food then a bedtime snack they stay full just fine.
