DD was 3, but that was out of necessity. The 4 year ds can't yet, or hasn't had the opportunity to need to. DS 9 yrs. old can but he doesn't like to and dss 13 yrs. old can but he makes a fuss about it. DH can just swallow them without water or anything, I don't get that. That would make me gag horribly and feel like the pill is still in my throat. At any rate, I think kids learn when it is necessary to learn. When they have to, they can figure it out. DD we didn't really teach her, we just said, "hey you can't chew this OK, so just swallow". She didn't have any problems. DS was old enough that he just kind of figured out what he had to do. We did tell him to use water to swallow it and he didn't like it but he figured it out. At the time, he had swine flu and was miserable anyway.Â
