Its never been easier to learn how to sit and strenghten the muscles required for sitting as it is now... with the bumbo! Alex and Eli both love sitting up and being able to look around. They have been sitting up for twenty minutes or so at a time and even when they're not in the comfy chair, they want to be upright and sitting as often as possible. Thank heaven for those people who come up with, design and manufacture these wonderful aparatus for the wee ones! In these photos the boys are 4 months old.
