How old is your daughter @romeskie. She's good in writing already. Me and my son doesn't reach in writing words of numbers but he already knew how to write numbers and letters.
Yes writing is learning not just about to write but to teach them to persevere in writing too. This is challenging because some kids have a short attention span.
She just turned 6 last month. I've been teaching her since she was 3 or 4-ish years old. We went through lots of tears, sweat, and so many hours of practice to get to the way she writes now.
Each kid has their own level of comfort when it comes to writing. Just continue teaching him, encourage him, and consistently guide him, he'll get there. :)
Ah okay, my son is four now and he is turning 5 on November 13. Yes i let him practice more and more. Thanks @romeskie
