Re: 10 month old: how much solids?
Will she self-feed? At 10 months, the easiest way to feed a baby solids is to ditch the spoons and let her do it herself. Self-feeding allows a baby to self-regulate very effectively. If she wants more solids, she'll eat what is on her tray and reach for more. If she wants less, she'll just play with them instead of eating them, or indicate that she wants out of the chair.
There are a lot of reasons why the guidelines for how much solid food to give your child differ so widely. First, there's just not a lot of good science on the transition from needing only breastmilk or formula to needing lots of solids. A lot of what is "known" is derived from custom and preconception rather than from data. Then there's the variation in when and how babies are weaned- most babies are weaned from breast and/or bottle by a year, and a lot of them are weaned abruptly. A baby who is being fed on demand at 10 months has very different needs, when it comes to solids, from a baby who is being nursed/bottlefed just a couple of times a day. And then there's the differences that come into play between different types of babies- some of them want and need a lot of solids rather early, others don't need them at all until after 12 months.
I personally like my pediatrician's advice about solids. She told me that until a year, solids are for fun with new tastes, textures, and motor skills, and that after a year, the transition to a majority solid food diet was often a slow one. She also encouraged me to watch my baby- if she seemed to want solids, let her have some. If she didn't seem interested, no worries.
The only time I'd encourage a mom to hold back on solids is when the baby is eating so much of them that it's impacting her desire to nurse. Breastmilk is the most complete nutrition you can offer, and it has got lots of fat- no need for butter on the eggs if she got cream straight from the breast!
At 10 months, breastmilk still meet a kid's liquid needs, so you don't need to offer a cup. But it wouldn't hurt to let your LO play with one, and to take sips of water (or milk, if you can express some) from the cup. Just for training purposes.
