Yes, yes and yes!! I could have almost written that same post

It's all very normal! They get really fast at drinking! DD feeds in just 5-10mins here too and only one side usually! Sometimes I offer both sides. But usually she's had enough!
It's great hey! Compared to the early weeks when she'd take up to an hour!!!

eta - my DD likes to comfort suck on my nipple afterwards too! And cracks up if i take her off even though she's finished feeding she's just comfort sucking I have tried a dummy but she won't take one! So you're lucky your DD takes one! however I don't mind cos its a habit I don't need to worry about breaking later on I guess.
