teach your c6 how babies are supposed to be taken care of.
routine and disciplined lifestyle
brainwash c6 that his mom''s way is bull shit
it will take a long time,,, but in the long run it will pay off
you better start brainwashing c6 as soon as possible
otherwise, you will only start getting more and more problems when you start feeding solids, the foods to give, the order to give the foods in, where to send to playgroup, whether to send to playgroup.....etc
Read books (english/chinese) or webpages (but don't show c6 baby-kingdom)
