The main purpose of swaddling your baby while she’s a newborn is to make her feel secure, warm and safe. After night months inside your womb, your baby will feel disoriented in the outside world, and the swaddling will help him remember her previous environment and rest.
After two months, many babies will start kicking and fighting the swaddle, while others are comfortable being ‘wrapped’ until about 4 months. Whenever you see your baby fighting the swaddling while he’s sleep or before falling asleep, it’s your cue to stop swaddling.
Swaddling a baby become a safety hazard once your baby is able to roll over, which usually occurs between 2 and 5 months. Once she has the ability to roll, you should stop the swaddling, as you don’t want her to be all tighly-swaddled and roll onto her tummy, since she could end up suffocating her, and certainly increases the risk of SIDS.
Swaddling also becomes a safety hazard when the temperature is high. Make sure you swaddle your baby on a breathable blanket, that is appropriate for the current weather conditions. As a rule of thumb, remember that babies should wear one more layer than adults, so do not overdress your baby as overheating is a major risk factor for SIDS.
Some babies don’t like being swaddled, though. If your baby doesn’t, you can try swaddling him a bit looser or leaving his arms out of the blanket altogether. To sum up, we recommend swaddling your baby during the first two months of life, if she looks comfortable like that; and read her cues after that as to when to stop swaddling.
