Yes Cammie is a big sister already! 
Oh donāt worry about structured teaching. In my opinion (and also mentioned in Domanās book), babies can learn anything that is presented in an honest and loving way. In my experience, planning a structure in itself consumes a lot of time and adds stress. lol I tried and there are so many factors that can alter the schedule I set so I just followed her interest. I just made sure materials are available everywhere we go (flashcards under the stroller, letter number foams in the bathroom, whiteboard in the backpack, etc). We also didnāt follow the rule for retiring cards and videos, I just followed her interest and trusted my instinct. The only structured material we used is the LR curriculum 
Are you planning to show your DS and DD the Glenn Doman Pict Dictionary? Itās a great way to learn general knowledge, reading, and has options for other languages too. Iāll be following your blog Happy teaching!
