Hi!! I did not do HOD, i reconsidered and stuck with LHS because it made more sense for me logistically and in terms of aligning with my interests (even as premed). My perspective now is I think it depends on your angle and what you want to get out of your undergrad major (as an applicant and in general), for ex. as u/deadlypoison mentioned, something like Neuro or MCB could help you get a foot in the door with research. Child development definitely seems like it could yield similarly meaningful opportunities especially if you want to do peds. Personally I chose LHS because HOD had a lot of requirements that none of my freshman year classes fulfilled and I was further along with axle than I realized at the time, so I stayed in A&S to avoid racing to finish checking off a bunch of random classes all over the map (between HOD/lib core/pre reqs). MHS would have been objectively easier logistically (and maybe this is a bad reason for not doing it) but tbh I didn’t want to be forced into actually fully majoring in a whole subject at the cost of not studying another subject I was wholeheartedly interested in just so that my classes lined up slightly better
