If you can manage it, let her sleep a bit in the basket. If she wakes up, pop her in a sling and see if she tacks on .... My LO2 was either in my arms or a sling at that age
General guideline - the first nap of the day is usually easiest to get in a crib or basket, start trying to start that nap in there by about 6 weeks, but don't kill yourself over it, you've enough on your plate. Just offer the opportunity to sleep independently and if LO goes for it, brilliant, and if not, help out. Newbies of 11 days old - loads of snuggles
