Sleep Sacks for Older Kids

My 16 month old daughter is a good sleeper and from the time she was about 5 months she has been in a sleep sack at night. We dress her in a short sleeved onesie and a long-sleeved sleeper and then put her in the sleep sack. Now I am wondering, at 16 months, is it bad to keep her in the sleep sack? I was wondering if it was bad for mobility and I asked our pediatrician at the 12 month appt. She said as long as it wasn't tripping her (it wasn't; in fact she is very good at walking around her crib in it!) it should be ok but she was also old enough to use a lightweight blanket in the crib instead. I tried the blanket last week instead of the sleep sack and of course it doesn't stay on her. Does anyone have any thoughts on this? My daughter is tiny (17 pounds) so she is still wearing the "medium" sized sleep sack. I know they make them in bigger sizes, too, so I'm assuming it's still ok to use them on even a lot older kids, but I just want to make sure I'm not stifling her development by keeping her in one. (My husband thinks that she feels all cozy in it and sleeps better because of it.) I'm just not sure. Thanks in advance for any thoughts.

What can I do next?

Hi, C.,

I had my son in one until age 3. He would kick the blankets off, end up head at the bottom of the bed, you name it. Besides, he liked the sleep sack. My daughter is 20 months now and same thing. We use the "early walker" style from Halo. It has feet holes cut in the bottom. I let her feet out so she can run around before bed. Then after she is asleep, I pull her feet in for the night! Works great!

My daughter is almost 21 months and still in a sleep sack. Mainly I have kept her in it because she loves it and it keeps her warm. I tried to take her out of it, but she got pretty upset. I don't in any way feel like it is affecting her development, she is running and walking and trying to jump just like any normal kid her age. I just haven't taken her out of it because I want her to sleep. They sell big sleep sacks through One Step Ahead. You can order online. I will probably take her out of it when she outgrows the one she is in now because it is the biggest size. Hope that helps!!

Hi C.,

My little boy is 25 months and has slept in a sleep sac since we stopped swaddling him at 4 months. I've decided that I'm going to keep him in it until we move him into his 'big boy bed' this summer and then we're going to use the grobag first duvet set

which is specifically for kids transitioning from a sleep sac.

If you don't want to do that, then I think doing it during summer is a good idea because then at least if she does get out from under the covers she won't get cold and by the time the weather cools down she may have gotten used to it by then.

Hope that helps. Good luck, D.

My son is 26 months old and is still using a sleep sack at night. He moves around so much while he's sleeping, so blankets are useless, plus he really does love it. Even on warm nights, he insists on it - just not bedtime without it. I think it has also kept him from climbing out of the crib, but definitely has not slowed his development at all. We'll be moving to the Halo Big Kids sleeper soon.

We used them up until my daughter was over 2 years old. Actually, we have some that are size 3T. They were great because she couldn't lift her foot up to climb out of the crib. She was cozy and happy. I tried to do the same with my other daughter, but she figured out the zipper and stopped wearing them around 22 months. She also started climbing out of the crib as soon as she got it off. Both of my kids developed totally normally and can run, climb and kick as well or better than all the other kids. They are also really good sleepers.

My daughter is 2 and still LOVES her sleep sack. She even wants it on for naps and honestly she sleeps better when she has it on versus not. It also hasn't hindered her mobility in any way and I am amazed at how well she can walk in it in her crib. I wouldn't worry at all. A friend's son used the extra large sleep sacks and now uses one as his comfort blanket and he's almost 4. I would recommend not fixing it if it's still working for you. Oh, and apparently they make sleep sacks for the much older child, I guess they just have two openings on the bottom in case the child wants to walk around and you are worried about tripping.

we segued from the sleep sack to the one-piece zip-up sleepers w/ feet. they work just great and since we keep the house at 67 degrees, the kids don't get too hot (our kids will be 2 and 3 in June).

i agree with the others. if she's sleeping well, don't change a thing!

I think they are great - especially in winter. Safe until the kiddo starts trying to climb out of the crib.
It's nearly impossible to get a toddler to sleep with a blanket so the sleep sacks were a godsend when our wiggly son was that age.
