I do not think it is a job, but yes, a lot of it are chores. Sometimes you derive pleasure from it, but other times you are just tired, hungry, without idea, the store is overcrowded with nervous people (particularly around christmas) the kid does not want anything and you really really just want to go home watch a movie or read pointless hacker news.
The romanticism of "enchanted work" and "making a magical experience for your very own children" is not realistic expectation. You don't have those magical feelings around activities and duties that happen with regularity. First, second time yes, eleventh time less so. Plis while the kids enjoy gifts, they are not really magical to them. Especially around christmas, they get more toys then they are able to play with.
And it really seems to me that those who romanticise child caring familly activities the most are either the ones engaged in them the least or the ones having ideological reasons. Stay at home mothers with no hobbies and whose life's centers children to the point of excusing everything else are the least romantic and the most pragmatic/mundane about it all - even as their only topic is the kid.
