Oh mama, I totally understand the struggle of finding the right pump, especially when you're a first-time mum and everything feels so overwhelming! When I was nursing my second one, choosing between all the wearable pumps nearly drove me crazy, so I really feel you on this.
From what I have heard around, the Youha Gen 2 is quite well-liked, one thing people really appreciate is that it comes with two flange sizes (24mm and 28mm), which is actually quite thoughtful since fit makes such a big difference for comfort and output. The heated flanges are also a nice touch that mums seem to love, and the app control plus decent battery life (holds up to about 6 oz) makes it convenient for hands-free pumping while you go about your day. My friend tried it for a few weeks and said the suction is reasonably quiet and it empties pretty well without feeling painful when you get the right flange size, though she did mention it took a little adjustment to find the right settings at first. On the downside, a few mums have flagged some reliability concerns after a few uses, so that is worth keeping in mind if longevity matters to you.
Overall it seems like a solid option with some really thoughtful features, but do check the fit carefully before committing, hope this helps, and wishing you a smooth breastfeeding journey ahead!
