After training Isabelle to have her meals ONLY in her high chair for so many months, today she proved that our hardwork and patience worth it all.
Went groceries shopping at next door mall with a friend and came home slightly pass her lunchtime. I told her that I will prepare her lunch while I put her down to play with her toys. She was probably very hungry already and anxious. She initiatively tried to climb on the high chair even before I stepped into the kitchen.
She now really understands her highchair is for mealtimes and it makes me proud :)
