Re: not wanting any solids
Everything is fine. My pediatrician says that until age 1, solids are just for experimenting with new tastes, textures, and motor skills. Breastmilk alone provides adequate nutrition. After age 1, solids become an increasingly important component of a baby's diet, but the transition from needing only breastmilk to needing lots of solids is a gradual one, so don't be surprised if your baby's diet continues to be mostly milk until well after his first birthday.
My DD barely touched solids until she was around 14-15 months old. We ended up doing baby-led solids because there was no alternative: she would almost never take food off a spoon. She's always been perfectly healthy, meeting her milestones ahead of time and on the high side of the height and weight charts,
