My DD is 3 months old ans only ever naps on the sling. We try putting her down in the cot every now and then but we never ever succeed so we always revert to the sling to ensure she gets enough rest during the day.
In the evening she settles fine in her cot (although only of she is swaddled, which is something we are trying to get rid of. But that’s a different story).
I don’t mind carrying her but I am a bit worried this could become an issue in the future. Did any of you have the same problem? How did you solve it?
