hmm. both has pros n cons. are you wking now? or you intend to hire a maid 1st? cos if wanna hire a maid, i think best is stay at hm with the maid and teach her hw to tc your son for a few mths until she is familiar with everything and also you can take the chance to know her better. In case not suitable, you can change her away w.o wrying that no one tc of your son.
Good about hiring a maid: they can help you to do hsewk when the child is resting or go to sch (presch next time). and 1 to 1 attention. Bad: if you hire a maid who is not good, then all the problems will come
If you want a CC, can start to source now alrdy cos some CC has very long waiting list. Finding a good CC is not easy too. =)
