Hay, I feel you mama, shallow sleep sa twins is REAL, and the constant waking and fussing during transitions is exhausting talaga, lalo na for a first-time mom! A few of us have twins din, and honestly, some babies are just lighter sleepers naturally, pero if they're still this restless and uncomfortable-sounding (the whimpering when they move, the frequent night wakings) at 1 year old, I'd still mention it to your pedia just to rule out anything like reflux, allergies, or even sleep discomfort, sometimes it's a small fix that makes a world of difference. You're not alone sa struggle, but your doctor can give you peace of mind and maybe some specific tips for your two! Hugs, mama, you're doing great asking around.
