	After being initially out of the first team, due to being suspended whilst at Hartlepool United, Baldwin made his Peterborough United debut on 1 March 2014 against Crawley Town, coming on as a late second-half substitute, and conceded a penalty in a 1–0 loss. Since making his debut, Baldwin quickly became a Peteborough's first team regular and helped the side reach the play-offs where they were unsuccessful after losing 3–2 to Leyton Orient. His performance was praised by Manager Darren Ferguson. At the end of the 2013–14 season, Baldwin went on to make thirteen appearances in all competitions.
