So my daughter is going on 6 months the 28th. Since she was a baby I would put her to sleep and set her in the swing. I recently started putting her in bed or playpen for naps. She doesn't sleep long!! Maybe 15 min. What should I do? Brake her out of sleeping in the swing?? Or put her back in it. Ftm so I have no idea what I should be doing at this age.
