My boy is reaching 1 year ...weight all along 75th percentile... But he eats very little solid... Each feeding us between 3-5 teaspoon of porridge... He can finish half a rice cracker and a few bites of apple.. I'm very worried that he is not eating enough for his age. Do you have similar experience and how and when did you overcome ?

Have you tried feeding different texture food like maybe soft rice or pasta? Some children dislike puree and porridge and like to go straight to "adult" food. You can experiment different types of food for him. As he is approaching 1, food source should come mainly from solids, so continue to introduce different variety and texture for him to see what he is more receptive to. My 8 month old dislikes puree, ok with porridge. She likes fish and chicken but dislikes pork. So it's all about experimenting with them to see what they like and not. Just like adults. Good Luck!
