    Not as advertised

    Nothing to compare it against anything.

    Snug alpine weather sleeping bag

    The little one is much warmer now in a 3.5 TOG as the temps in our house can drop down to 14 degrees overnight in the alpine climate.

    We love ergo. Here for the longhaul.

    At first they seem expensive. But even if you used it 10 times, that's just $6 per use. Obviously, you'll use them A LOT more than that.

    I really believe bub being comfortable at night has helped him with his sleep.

    I was very on top of making sure he was dressed appropriately and it paid off. Not gonna lie its challenging at times, since overnight temps drop etc. But tuck sheets for bubs work a treat. As you can put on & off. Toddlerhood is a bit harder. We resorted to just bringing him into bed if temps dropped too low & he woke. But still he'd get through MOST the night, snug in his ergo. Plus not much more you can do to prevent that.

    My only suggestion, by them as needed. Not in advance. You better know what they need fir what size and weather at the time.

    And there's sales every 4-6months, so you dont need to worry about chasing those.

    I tried a cheap tog, and it was Polyester and he sweat in it so bad. So do recommend these. They breathe and are beautiful and soft. Plus you can always sell them on marketplace later if you look after them.

    (BTW, dont use napisan on them, just general wash is enough, napisan makes everything go crispy and gross, ruins the fabric).

    Hope this helps.

    Much love mummas. 🩷
