Is swaddling required for a UK newborn?

No. It is a comfort wrap some families like in the startle weeks. It is optional. Keep hips free to move. Stop as soon as they show signs of rolling — arms must be able to push up. A muslin is not a cot quilt. If they already sleep in a bag, you do not need a wrap as well. NHS and Lullaby Trust pages still win on sleep position.

When is a sleeping bag the better product?

Once arms are free, and for most of the first year. A bag is a wearable blanket so you do not use a duvet. Match TOG to the room, then check the chest. Skip extra blankets on a 2.5 TOG bag in a warm room. Use the TOG calculator after you can measure the room. Read sleeping bags.

Are weighted swaddles or bags a good idea?

No as a house buy. UK safer-sleep advice does not want extra weight on a baby in a cot. We will not hop you to a weighted wrap. Bags without proper armholes and stretchy necks are a skip even before a recall. Check OPSS if a marketplace listing looks odd.

Can you use both in the same night?

Not as a stack. The wrap or the bag is the layer, plus a vest or sleepsuit. Two products that both pin or both add TOG is how overheating starts. Transition styles that open the arms are a sequence, not a double wrap. If they are sweaty at the chest, remove a layer now. Hands are a poor guide.
