Personally, after much thought, prayer, and conversation with my primary president, I chose:
Page 86 - "An Angel Came to Joseph Smith" (Related well to April and May themes; will teach this one in April)
Page 142 - "Every Star is Different" (Related well to overall theme; will teach this one in May, with June as a back-up, since the children know the June song very well, having sung it in the primary program last year.)
I will be posting about teaching these two songs soon of course, but I may focus only on teaching Mother's Day songs this coming Sunday ... post to come by the end of the week.
