Weaning breastfed baby

Rika

I’m a first time mom and my son is turning 12 months old in a month. My plan was to stop breastfeeding at 12 months but due to the coronavirus outbreak I’m working from home and thinking of maybe continuing a bit longer. Is it more difficult to wean off breastfeeding when baby is older than 12 months old? If yes then I may want to wean him. And how do you do it? If my baby wants to breastfeed do I just not let him at all?
