This is repost but I still need help. I am still very torn. I am not sure I can handle running K and 1 concurrently. ODD is ready for OM1, except for math which I will supplement with singapore 1a/1b. YDD would do well with the K, no doubt, but I think she could handle a lot of the 1. My issue is that 1 is obviously 2 years ahead and in the next couple of years, the difference would show. I do plan on using OM for the next few years. I know NOT combing might be best. What do you think?
