Do you remember this magnetic drawing board thing from your own childhood that you write with a pen that had a metallic end and can be cleaned with a swipe of a tab across the board? Like this:
I just got Sophia one of these from a neighbourhood shop and it was such a great decision. Just yesterday when I came back from work she jumped up saying “mama.. mama..” and headed straight for the board. Once she laid hands on it, she started drawing squiggles that look like nothing but curly pig tails mumbling “m..o..m..p..” (basically a sequence of alphabets that didn’t make sense) and proclaiming “Mummy!” We all clapped and said “well done!” and afterwards I demonstrated how mummy is really spelt by writing and saying it out. I hope she’s not actually supposed to get it at 22 months though, because the next time I asked her to write mummy I think she mumbled “m..o..p..q..” and walked off.
