cindy,
most prob and best option i think will be the 1st one.
ting,
my mil is already 61 yo.
she is a housewife.
since my sil give birth, the 2 kids are in her care till now.
then my sil is a divorsee. so 2 kids and herself is a PR in my mil house.
for now she is busy with the 2 kids and the household. althought the boy is sec 1 and the gal is p4.
whole family depends on her to cook, and all.
also my sil is super hao ming one.
she dun have to do anything. just wash her own under garment, the kids tuition also my mil cycle to fetch thro and fro and my sil just after work, stay at home watch TV.
she dun do house work and dun cook. dun teach also. unless kids dunno then ask her. she more to the bo chap mother.
so i foresee, when inez is in p1, the boy will be in poly or JC. the gal will be in sec 2.
so i suppose mil will be able to help me take care of inez.
