Hi,
My dd is 21 months and just recently I've noticed whilst she's playing she'll sometimes line things up. Like little toy characters, crayons, puzzle pieces and sometimes finger foods. She doesn't do it for s long time and doesn't get upset if they're moved. Ive read about schemas and wonder if it's one of those? Maybe the connecting one.
Everything else with her development seems ok. Her talking is coming on. She says lots of words now and joins some of them together. She's very alert in every way. She's affectionate and loving and pretend plays with her teddys and dolls.
Any advice would be good :)
