DS(1) 16 months seems so demanding, doesn't have any real interest in toys (unless I am playing on the floor with him giving him 100% attention) and has a very short attention span (compared to his peers). It's starting to concern me. For example, we went to a friends house yesterday and while the other 2 toddlers were playing with toys DS wandered around, whinged, or tried to climb on me. He's also like this at a mother and toddler group we go to. He's always demanded a lot of attention and it's very hard going some days. Anyone else had/in a similar situation? Should I be concerned?
