what is food recommend to my boy gain a weight an height .which he will likely have to eat

A. To increase your child’s height, it is integral that he has a proper posture. Slumping or slouching can put unnecessary stress on the spine which can have many negative affects on the body. Additionally, poor posture can alter the shape of your child’s spine which can compromise his growth. Make sure that your child practices good posture not only to increase his height but also to prevent any long term health issues. Remind him to sit and stand up straight every time you see him slouching.https://parenting.firstcry.com/articles/top-8-ways-to-increase-height-in-children/
