He's been in school for a few years now, starting at 2.5, now 4.5. Both his teacher last year and I noticed he is very handsy with other kids. His sensory seeking is along the line of lots of hugs, touching, grabbing their neck (lovingly). And he has other sensory sensitivities to loud noises (covers ears), eats very limited foods, and more like chewing on things he shouldn't (as a preschooler). We had him evaluated with an Occupational Therapist and he scored very high on their sensory sensitivity questionnaire. He also is very touchy with me and Dad too. Excessively so. We are constantly redirecting with stuffies, squish toys, chew toys, etc...

A lot of this stuff can fall under normal behavior, especially in babies and toddlers so it's almost impossible to know when they are so little if they have sensory issues. But looking back I can see his quirks when it came to sleeping and breastfeeding were early signs.
