Just wondering if anyone else's LO's had obsessive behaviours as a toddler. Is it a normal developmental thing? My DD is 20months and has stopped playing with her toys but instead will pick 5 or 6 items and move them 1 by 1 from say the sofa to the chair and back again. She is totally engrossed when doing it. She will also bring me things to hold and will get quite annoyed when I can't hold all the items she brings me in my hands! Is she being odd, or is this just something toddlers do?
