baby 1 month old hepatitis B second dose @ polyclinic

initial appointment date was 20 May but postponed to 1 June when my baby is 6 weeks old, went home after vaccine. no physical examination at all even though health booklet shows there should be for 4 to 8 weeks checkup. nurse only say 3 month checkup, will do the 3 month physical check. what about the 4 to 8 weeks physical examination? why do they skip? or do i need to book a new appointment for 1 month physical examination?
