I think the baby tracker should have something about milestones perhaps noted with a star on the tracker or something.. Such as "Rolls from back to belly" "First laugh" "Sits up", or "First tooth" etc. I also think the "number of bottles" section should be broken down into two, more simple questions, that are more easily answered such as "Ounces per feeding" and "Hours between feedings" or something like that because that's what is more important when it comes to feeding.
Other than that I think it's great. :)
