my son is 2.7 years old and his weight is 10.5 kg is it normal for this age group ? could you suggest tips for weight gain

A. Hello mom it is slightly on the lower side , so would suggest not to worry a little variation is acceptable as far as the child is active for his age . Give him dry fruits and nuts, lentils and legumes, eggs, milk and products, stuff paranthas, milk shakes , etc
