Aww, nakakasawa talaga when baby's afraid of pooping, mama! Since constipation can be tricky and might need specific formula adjustments, best to run it by her pedia ulit, maybe she needs something with different fiber content or a formula na mas gentle sa tummy niya (some brands like Similac, Enfamil, or even local ones like Promil have different variants for digestive health kaya maraming options). In the meantime, make sure siya really hydrated and maybe add a bit more fruit/veggies na natural laxative effect, pero yeah, doctor's advice talaga ang best bet here para makita kung ano exactly ang need niya!
