Transitioning from long sleeve to sleeveless sleeping bag

[Melissac88]

My 11 month old daughter has been in a sleeping bag (a swaddle at first when she was little) since birth, and always been in a long sleeve one. She's outgrown her current one and I can't find many in the next size up. All on amazon seems to be either smaller or bigger than what she needs or crazy prices elsewhere. I think we are going to have to try a sleeveless one, but don't their arms get cold just with a sleep suit on underneath? Has anyone gone from a long sleeve to sleeveless? I'm not sure if she will take to it

Are you searching for the right thing? I put sleeping bag 12-18m in amazon and got plenty of sleeveless ones. They tend to go 6-12, 12-18, 18-36m.

It's easier to go with sleeveless and a long sleeve vest or pj's, especially as it gets a bit warmer.

Yeah I can find plenty of sleeveless but I was planning on getting her another one with sleeves in age 12-18months but there seems to only be younger or then a couple 18-36m, baring in my mind I'm looking at 2.5tog ones. All the 12-18 long sleeve seem to be extra thick 3.5tog.
sorry didn't make the post clear!

It is likely she doesn't need a long sleeve one to be warm. I live in Scotland and our house was pretty cold when my DC were small and they only ever had sleeveless sleeping bags.

Do you have the chart that shows how many layers are needed for bed for the temperature of the room?

Never used one with sleeves for mine. Just used a long sleeve pj underneath
