Sleepsuits should always have a snug, yet comfortable fit on little ones for safety reasons.
To measure a small baby, lay them down and place a measuring tape alongside them from the top of their head to their bottom of their little heel.
For those one their feet, you can measure them standing from head to heel too.
If your little one is nearly the size up, we always recommend going for that size to make sure you and them get the very most from your sleepsuit.
