I've been swaddling dd (19 weeks) since birth. I feel the swaddling is a huge help as sometimes if she is overtired she'll almost magically calm down when I bring swaddle across her arm, and at night seems to resettle well too (though not in day!). I now leave one arm free, sometimes both. I'm nervous about ending swaddling though and would love tips on how to ease her into a sleep-bag. Thankyou all.
