If an unbaptised person died it was thought that he/she would not be received into heaven: so if a newborn or unbaptised child was thought to be unlikely to survive, a fairly common practice was for a baptism to be arranged at the home. This would usually, but not always, be indicated in the register by a 'P' or 'half-baptised'. If the child subsequently survived, a full church baptism would be held, again usually, but not always, marked in the register as 'received into the church'.

Hopr this helps.
