At 7 months, kung exclusively breastfed pa lang, honestly the breastmilk pa rin ang best source ng nutrients niya, pero marami na sa babies na nag-start ng solids around this time, a few of us give iron-fortified cereals or pureed meats kasi importante talaga ang iron sa edad na ito. Better mag-consult with your pedia though para alam mo exactly kung ano ang kulang sa baby mo, kasi bawat baby different eh, at they can recommend the right supplement based sa feeding plan mo!
