Adrian has been writing in his workbook almost daily (buy here), and he has completed all the straight-line letters, so we will be moving onto the curved ones, like C, G, S, which are much harder.
Adrian loves the Humpback Whale (buy here). He is also using the Blue Whale (buy here).
Adrian is using these gel ink pens.
p.s. See here Adrian tracing upper case letters at 38 months. Now, at 39 months, he is more confident as his movements are more precise and refined. Practice, practice, practice!
