This could all be quite benign, it 's difficult to know. At this age, most children have a vocabulary of 200-300 words, so your son is definitely at the slow end of the spectrum in this regard. Now, does this mean that his development in other areas is slower than what might be expected? Not necessarily, but it's a distinct possibility and should be assessed. You do not have to adopt an all-or-nothing appproach in regard to satisfying his need to embrace your hands, but definitely do not automatically gratify his wish, and continue to offer alternatives. It may not be the best idea to join him in the morning, because you may be exacerbating his need to have you close to comfort him. You can now gauge the amount of sleep he gets each day, both during his nap and overnight. Try to solve the early morning situation by altering his bedtime at the other end (at this age, children normally will sleep approx. twelve hours overnight).
