My poor darling is sick again

Baby Derrick is sick again, 2nd time in his first 6 months of life. Mommy is feeling guilty for not responsive enough to detect the abnormality in him. Even worst, mommy left him yesterday night with daddy and went away happily shopping with XG. Hai, when mommy came back, Derrick was already in slumberland, but he woke up crying in pain past midnight. Mommy thought he was having 'wind' and just keep on stroking his tummy with medicated oil. Mommy did realize that Derrick didnt finish his milk though. This morning , baby woke up early at 6:15am and again refused any milk but water. Stupid mommy has yet to realize that something is wrong with baby until Ah Ma triggered that baby might be having soar throat. What a lousy mommy ! Later gonna bring him to the doc, and this is the least I can do to ease his pain.
