Disturb sleep

I am a first time mom. My bby is now 4months and 12days old. Putol putol po lagi ang tulog ni bby. Ako halos wala na sleep kskabantay at walang kapalitan. Kamot sya ng kamot sa ulo nya. Madalas ikot ng ikot hndi mapakali pero naka pikit po sya at antok na antok. He still have his cradle cap. He also diagnosed a month ago with atopic dermatitis. I really dont know what to do na po. Ginamit nmn nmin yung reseta ng pedia derma, nawala sya after 2weeks pero ng stop na kmi, bumalik nnmn.
