Re: 8 months old and still no interest in solids
My kid didn't really get interested in solids until 14-15 months, and she did just fine. At 4, she eats a terrific diet- she's the only kid at her preschool who comes to school with salad and also actually eats it.
It's totally normal for an 8 month old to show very little interest in solid foods. At under a year, solids are just for experimenting with new tastes, textures, and motor skills. They're not nutritionally necessary until after the first birthday, at which point the transition from needing only mama's milk to needing a ton of solids is a gradual one, with many babies not eating more than a token amount of solids well into their second year.
The only thing you should be doing is putting a variety of healthy food in front of your kid. If he eats some, great! If he just tastes it and spits it out, or just plays with it, that's fine, too, because even when the kid isn't actually swallowing he's still learning about solids. Don't stress and don't get sucked into the trap of offering junk food just because it's the only thing he'll eat.
