Re: 11month old won't swallow anything other than breastmilk
Not to worry! Until the first birthday, a baby can stay well-nourished on breastmilk (or formula) alone. After the first birthday, babies start needing solid foods, but they don't go from needing zero solids on day 364 of life to needing a ton of them on day 365! The transition is going to be slow, with a lot of babies not eating a majority-solids diet until well into the second year of life.
Just keep offering a variety of healthy options (don't fall into the trap of only offering things you know your child might eat), and be patient. Your baby will get there.
