When to start booking for confinement lady?

Hello ladies, ftm here, would like to know when is it a good time to start looking into confinement lady? I actually asked for quotes and they kept saying that it's almost fully booked. So I'm not sure is that just a sales tactic haha. And if there is any good CL recommendations please help too! Please advise 🙏🏻#firsttimemom #advicepls
