Hi my son is 1.7 months old and he sits with hunch back. Is this normal. If I tell him to sit straight he sit for few seconds and again he come to same position. And one more question is that he always sit in w position. Elders say me to correct it but if he tell him he sit properly by leaning his legs or else again he sit in w position. Please suggest whether he can sit with hunch back and also in the w position. Please do guide me with this regards.
