I have to think about this a bit, but for starters, I could tell you that small/narrow tubular flowers that attract hummingbirds tend to be mainly visited by the more gentle bumblebees in my garden which is planted for butterflies and hummingbirds. They are likely visited by nectaring moths at night as well. The flowers I'm thinking about in particular are native coral/trumpet honeysuckle, Monarda, and runner beans.
The vining plants have the added benefit of easily being trained on a trellis around or near windows for close-up indoor viewing.
I don't know what butterflies are common to your area, but you could possibly plant mostly larval food plants rather than nectaring flowers. Carrot, Parsley, Dill, and Fennel for the Black Swallowtails, Milkweed for Monarch butterflies, etc. Flowers of these plants are tremendously popular with butterflies as well as bees and wasps, but you could cut off the flower buds before they bloom if you are truly concerned. Research other food plants for what would work for you.
The benefit of planting larval food sources is that the butterflies will come into your garden to seek them and lay eggs, and you will see freshly eclosed butterflies flying around in their crisp new colors. The more native food source plants you have, the more varieties of butterflies you will glimpse. I have spotted some unusual ones. On two occasions, they were not listed in the Butterfly and Moth database for my area and I reported them.
Planting the nectar sources at the far end of the garden, planting flowering trees, or hanging baskets, well above your baby's head might be other options.
