my baby turned 7 months old today and is always crying

radhika

since i think from before 1.5 months he always has been crying. went to doctor like every week but he is fine only. only wants me whole day. allergies are also ruled out. now i am at my wits end, even when i hold him, he cries. no teething. nothing. he clamps on my nose, scratches my face, pulls my hair very rough. i always tell him in calmer voice to be gentle. sorry if my post is too random, but i nded some advice.
