Mummy who didn't put lo in infant care .. Do you think your child will be slower than others who had put in infant care.? do you think I should enrol my lo at 18 months or 3 years old ?

My LO is also not infant care and is being care for by my MIL. At 18 mths she already can speak single words (both in Chinese and English) like: sit, climb, please, thank you, bus, bear, ball, throw, bye, bag, etc She can also point to me where her body and face parts are. So even not in infant care, development is not slow.. is more of the exposure..
