Keeping arms warm in a sleep sack

How do I keep DDs arms warm in her sleep sack?

She has been sleeping without being wrapped this past week and I've had her in either a long sleeve onesie with mittens or a t-shirt one with socks on her hands.
Is that enough to keep them warm?

At the moment, as it is summer, Jude wears a t shirt or light long sleeve depending on the temperature.

In the wintertime he would wear long sleeved pyjamas, onsie or nightgown in his sleep sack. His hands and arms would still end up getting cold, so I bought some merino leg warmers and put them on his arms with the ends pulled over his hands to keep them toasty (We lived in Dunedin at the time, it was cold! )

If you're worried about her arms, maybe you could try a little cardigan (merino?) but not do it up? That way it will not make her torso too warm, but add that extra layer to her arms?

Having said that, I used to worry about Jackson, but my midwife said that their hands etc can get quite cold before they actually care too much - they key is that their bodies and heads are warm.

Well done on starting to get C out of the swaddle! I am not brave enough yet. :)

We just used a long sleeved onesie and bought merino cardigans from jk. We also had a temperature controlled heater in her room.

I like the idea about the merino leggings though.

I used to put a knitted bolero (sp?) on DD if she was chilly - its kind of like a cardy, except it's only the sleeves and a little piece around the back.
