Congrats sa 6 months milestone, mama! We started with iron-fortified rice cereal mixed with breastmilk, tapos after a week or two, one of my mum friends introduced banana (so easy to prepare lang talaga), and that worked well din. Go slow with one food at a time para makita mo kung may allergies, at start with just a teaspoon or two kasi getting used lang ang tummy nila sa solids, some babies take to it right away, others need a few tries pa bago gusto nila, and that's totally normal!
