I just bought an Ardo Calypso double pump in the hopes it would reduce the ridiculous amount of time I'm currently spending pumping to keep up with DD's needs now I'm back at work. I used to reliably get 75ml from a 40-min evening pumping session with my Medela Swing, but last night I tried the Calypso and barely got a drop over an hour. I've tried single and double-pumping with the Calypso and either way I just really struggle to get a let-down, something I never had a problem with before. I must admit I struggle knowing how best to set the volume and cycles settings. Any tips from anyone who's used this pump?
