If you have your own mum to take care of baby at least till she's about 3 years old or so, will you continue this arrangement or send your baby to school earlier. Why and why not?

No matter who takes care of my child, even if it was me myself, i would definitely send baby to school. Child care is not just about placing your child there. Your child gets to interact with other peers his age which is needed for their growth. Also early exposure to school settings. At the sametime the caregiver can have selfcare. There are also activities catered for oe their age. Its better then being stuck with us the whole day.
