So, it's really
keeping them out of those
areas and setting up the
areas for your older children that they can
play in, with those toys like the Lego's or you know the dolls or the clips and stuff that have little objects and then they have other
areas where the older child can
play with the younger child for age appropriate toys, so that they can
play together by
keeping the non - age appropriate toys either in a
separate room or in that older child's room so that you can
keep them
separated and not necessarily have to baby proof that older child's room, because It's gonna be nearly impossible to do.
