Do my baby's tummy ready for solid food?

Si Pedia nong sinabi nia sakin at exactly 4mos si Baby, nag hesitate ako and I asked him na dba dapat 6mos, sabi nia depende daw yun sa capable ng bata, nakita siguro nia na pwede na pakainin si lo at 4mos. Sinunod ko naman panay steam and blended foods, veggies, fruits and sometimes lugaw na may mince chicken. Ok naman si Baby, and I think mas ok ngang ma introduced agad sila sa foods para masanay talaga, and basta ba may signal na si Pedia.
