Totally up to you ~ there are no regulations for this unless you are with an agency in which case you would have to have 'Infant and child CPR and Emergency First Aid' .... the level A,B,C, D varies depending on how the company offering it defines it so I would be ensuring it has the 'infant and child' component.

This company offers a combined First Aid and CRP options tailored specifically for home childcare ~ this is what I take annually as it is offered through our local OEYC and is the least 'time' restraint and cost effective way to take it .... other combined courses charge MORE and while the First Aid is good for 3 years the CPR component is only good for 1 year so you have to take than annually anyway to say you are 'certified' ... it typically costs more to get the CPR itself
