On a typical Sunday DL crowds are light until about 10am-11am and then they start to build. On Mother's Day the build up starts about an hour later than usual. Judging by the number of women carrying flowers in the park, it's a popular destination. The DLH is not having their typical brunch this year, but my guess is that won't thin crowds. Plus next year there will be a half marathon, don't see that decreasing Mother's Day crowds either.
