Hi mama! Congrats sa 6 months milestone! Honestly, better to introduce formula gradually talaga, a few of us did it overnight and our babies had digestive issues, so maybe start with one formula feed and slowly increase over 1-2 weeks para hindi ma-shock ang tummy niya. For the solids, you can start with simple purees like banana, sweet potato, or rice cereal, and introduce one new food every 3-5 days para ma-monitor kung may allergies; personally I did 1-2 feeds of solids at lunch time first habang continued ang formula at breastmilk pa rin for the rest of the day, pero ito talaga better to discuss with your pedia kasi bawat baby ay different! You're doing great with planning ahead, ang dami ko pang tips pero seryoso, get your doctor's input on the transition plan para sigurado lang!
