My son is 6 months old, well almost 7 now, up until now his motor skills have generally trended to be about month earlier than on average, but crawling and scooting are at the same stage they were 2 months ago almost non existent. Sitting up requires more support now than it did when he was 4-5 months old. I won’t be concerned until around nine months when he should be able to do some bipedal support on his own.
