My 5 month old is outgrowing her miracle baby swaddle and I want to transition her to a gro bag but if her arms are free she wakes herself or is v hard to get to sleep. We tried the love to swaddle 50/50 but she can't get on with having her hands up by her head. The woombie looks like they have their arms free in front of them within the sack, is that right? Does anyone have and swaddle wisdom they could share?! Thanks so much in advance.
