Self weaning?

My daughter is about 10 months old (on the 12th) and she is just getting over a stomach bug but she hasn't been wanting to breastfeed as long or as often, like 2-4 minutes of breast feeding every 2-4 hours and she fusses when I try to get her to finish (usually takes her 5-6 minutes) and she doesn't want me to rock her to sleep or hold her until she falls asleep, she just eats to lay next to me and falls asleep on her own. Not complaining about that part but she's just been like this the past 2 days, out of no where. Is this going on with anyone else?
