The 10.5 mo infant could simply be at a weight plateau. I've seen this before. If the baby has gained weight steadily prior to this, I'd worry less. At 10.5 months, 17 lbs is somewhat light, but I can't comment without knowing the baby's height and build (baby is a normal weight if she's short). Babies eat less well when they're sick, so it's not unusual for weight to plateau if baby hasn't been eating well due to a cold or two. A 10 mo infant can certainly take extra fluids from a cup and should be eating a variety of solid foods. I would let the baby breastfeed, but also encourage additional calories from cow milk in a cup (even if mom has to hold the cup until the baby learns to use it herself--bottles should disappear on any infant by around 12 months of age, so starting one at 10.5 months is just silly), and lots of frequent solid food feedings.
