Mommies pwede na ba kumain ng biscuits pang baby ang 4 months? ilang months pwede pakainin ang baby? If pwede any recommendations?

my pedia advised 6mos.. i started with cerelac and gerber saka teething biscuits. saka small portions lang muna sa umpisa introduction pa lang naman like 1-3teaspoons lang . then nung medyo nasanay na din sya tinaasan ko na dami since nag eenjoy na sya and also i started mixing real vege and fruits na din. wag mo sis biglain masyado si baby sa solid baka magconstipate. wag din po palagi pakainin ng foods na nagpapaconstipate like banana wag po regular basis like everyday.. pero d naman po ibig sabihin na d nyo sya pakainin ng banana wag lang po araw arawin. tapos lagi nyo po check poop nya. si baby ko it took her sobra 1month na mag adjust sa poop nya totally dati kc nung milk lang sya creamy poop nya. nun magsolid na sya medyo nabawasan creaminess then nun madami na sya na kakainin actually nagconstipate sya umiiyak sya everytime na poop sya.. what i did is cut ko muna ung nagpapaconstipate na food like banana, squash. ngayon ok na poop nya malambot na ilabas and tamang moist lang. she loves brocolli, papaya and oranges..
