I agree that you can consider to let Egg Egg to attend full day school.....in school he will get better attention and food.
In my situation.....my 99 can only take care of Siu Sun's food but no others ( she cannot communicate well and play with Siu Sun ) and sometimes she even did some terrible / dangerous thing to Siu Sun.
By now.....I am less worry about her in school... which is good for Siu Sun and me....
