You mentioned he was baptised in Nov 1846
If he died on 19 Sept 1851 age 5 (as per GRO cert) he would have been born between 20 Sept 1845 and 19 Sept 1846.
If he was buried on 21 Sep 1852 age 4 (as per burial record) he would have been born 20 Sep 1847 - 19 Sep 1848 (assuming burial 2 days after death).
I suspect there was a mistake made when recording burial in parish register. Many were written up a lot later than the event.
