## Questions & Answers

**Q: Is there much difference in the amount of extra fabric at the bottom of the 6-18 month and universal size sacks?**
A: I bought size 6-18 months for my kid since he was 2 months old and then I got 18-36 months when he turned 12 months.  He is almost 18 months now, still using it fits well.  There are enough extra farbric at the bottom for him to turn around if that's what you were asking.

**Q: What size should i get for a 14 months in early October? Baby is 30 inches, 26 lbs. Ideally we could get two winters use from one item.**
A: Woolino 4 Season BASIC sleep bags (standard sizes) - THIS LISTINGSize                           height                 weight  0 - 6 months;  22-27"  (56-69cm);  10-18lb (4.5-8kg)6 - 18 months;  26-33"  (66-84cm);  16-27lb (7-12kg)18 - 36 months;  32-39"  (81-99cm);  25-36lb (11-16.5kg)Woolino 4 Season Sleep Bags (universal sizes)Size                               height                     weight2 months -2 years;  23-35" (58-89cm);  10-32lb (4.5-14.5kg)2 - 4 years;   34-42"  (86-107cm);  26-42lb (12-19kg)Universal size listing link:http://www.amazon.com/Woolino-Season-Sleep-Merino-2mo-2yrs/dp/B004FJL92K

**Q: What is the actual length of the fabric for each size sack? Not the length of the baby, but the length of the sack?**
A: Woolino 4 Season BASIC Sleep Bag Lengths (standard sizes)Size			Length 0 - 6 months; 	27" (69cm)6 - 18 months; 34" (86cm)18-36 months; 40" (102cm)

**Q: Baby is waking up multiple times legs/feet as well as arms are cold to touch. Room is 69/70, should I be using wool pjs underneath as well?**
A: Yes, at 69f you may dress your child with long sleeve pajamas, wool or cotton. Here are the dressing suggestions on the back of paper thermometer that came with your sleep bag.Touching hands or arms is usually not a good indication of a child being cold. Touching their belly or behind their neck while they sleep will indicate better if the child is hot or cold. Also, please note to place the room thermometer in nursery on the crib level to make sure you're getting the correct readings. I hope this helps.

excellent product

### ⭐ I had to return it before we even tried. ...
*by A***N on 6 October 2017*

I had to return it before we even tried.  It is so thin!! It is literally cotton outer lining and a very very thin slightly fluffy woollen fabric.Even if I assume that this product is some sort of NASA mirracle material that can replace blankets and duvets, surely it will bobble up and loose its miraculous quality.  So I have to be honest and admitt, we haven't tried it. But I can't take a risk at the expense of my baby's health.
