Ds is 14 months (just) and seems nowhere near walking. He can stand but usually holding something, though he can stand alone and has done a few times. He will scale round the playpen and climb at soft play etc but has zero interest in walking at all. Should I be concerned? It says online the average is 12 months, does this mean he’s not going to be very bright? Or any other things? First time mum with not much partner support, worrying a lot.
