I used to use Aishiteruze Baby as my shoujo example for a group of four, but Gakuen Babysitter is even more about the childcare aspects and is actively a comedy and so more comparable. Romance Papa is pleasant, but very much not about the parenting but rather the teenage daughter's romcom school life.

Lolicon is indeed a shoal of jagged rocks lurking in those waters. I'd forgotten about Blood Alone -- I didn't bounce (largely because a) the guy is clearly Not Interested and b) I was able to squint enough to read the old child vampire's acts as symbols of her desire to Grow Up in a way she never can) but it's not exactly my favorite. Many of the others are indeed even more skeevy, leaving one to either age down to Yotsuba or slant drama as Bunny Drop or My Girl.
