Upon executing a missed approach; the aircraft was leveled off early. The error was recognized and the aircraft put back into a climb to reach its target altitude for the missed approach. Pilot flying became disoriented after the acceleration and climb on the go-around in IMC. The aircraft was light and the majority of experience was on the Y series. It had been 15 days since the last flight; and 76 days since flying in an X [series] for the pilot flying. The PF reaction to the increased pitch attitude and acceleration was to level the plane prematurely.[Need] Review of SOP procedures for go-around; and mental preparation for pitch attitude changes from the Y to X series on the X type aircraft on takeoff and go-around configurations.
Air Carrier First Officer reported not following SOP's during a missed approach and stated that an extended period of time off was a contributing factor.
