FIrst time round I was super relaxed about weaning. Second time round, I read all the Science of Mom stuff and was all about the meat and fortified cereals... Also, vitamin D and fish oil daily.
I am much much tougher about accumulating toy clutter and rubbish this time. Wish I had been stricter with my eldest. The relatives mostly give consumables now.
Regular dentist checks from a really early age. My eldest has never had any problems, but I am not taking any chances with this one.
