I'm sure the boys have indicated when the last time they saw their sister was. I don't recall seeing that information in the media at all. Can someone refresh my memory as to what type of "meal" an 11 month old baby would have before bed? I know they are still on the bottle (I guess Lisa was not breast fed) but don't they have a pretty good solid food diet at this point too? If so, then I would think the boys at least must have seen Lisa at the dinner hour.

It really depends on the baby's preferences and the parents' parenting philosophy. We practice something called baby-led weaning, which means nothing but breastmilk for the first 6 months (no formula, no water, no solids). At sometime between 6 and 7 months, we introduce veggies - cooked until they are soft and then cut up into little tiny pieces so the baby feeds herself. No spooning pureed food or watered down cereal, etc. The saying "Before one, solids are just for fun" is popular with the BLW crowd. Breastfeeding remains the infant's main source of nutrition for the entire first year, and they just get solids once or twice a day for practice in terms of taste and texture.
OTOH, I know other people who formula feed, put rice cereal in the bottles and start pureed solids at 3-4 months old. These babies are often eating 3-5 jars of pureed baby food per day by the time they are 10 months old.
I also know a family who had a son with sensory problems, and he couldn't chew regular food until he was almost 2 years old.
So, all that is to say, it really just depends on the family and the baby. I can answer for my family - at 10 months old, I would have given her veggies, meat and fruit diced up without any sauces or seasoning (if I'm making tacos, for instance, I'd take a little bit of the ground beef out for her before I added in the seasoning packet; likewise I'd take out a scoop of green beans before I added salt, etc). She'd eat maybe half of what I gave her, thrown the rest on the floor (lol), and want to nurse right after dinner.
I will also say that I don't think it is unusual for a 10 month old to nap at 4:30 p.m. Especially if she was sick. IME, babies and toddlers sleep a LOT when they are sick. Even big kids do, really. My oldest was home for 4 days with strep a couple of weeks ago, and she pretty much just slept and watched a little TV the whole time. This is a very energetic kid, and she was just zapped.
All MOO, of course.
