Brilliant quiet well built pump, kindly and efficient customer services. The only development I would like to see is on the expressed baby milk delivery end of the process. The bottles supplied with the kit are small and old fashioned and do not come with their own teats. I would like to see Ardo develop their own modern bottle/teat combinations that mimic the performance of a mother's breast, especially for when baby is at the 0+ stage of feeding and life. I spent a great deal of time trying to find a teat that would.. a.) fit directly to the Ardo bottles, to avoid decanting/double handling/washing up - these are old style "standard" 25mm diameter neck size, and of greatest importance to my baby.. b.) slow enough to make him work as he does on the breast, instead of monstering 100ml in one go then burping half of it back up again! We are on our fifth bottle/teat combo in as many weeks, and are currently having very good results with the Haberman Suckle Feeder. For now I will pass over in silence concerning the other four "slow flow" teat designs, unless you would like to get back to me on this. I have a background in design and engineering, and baby is not inclined to colic, and hopefully never will be.
