1 year old suddenly obsessed with booby!!

I haven't been on her in sooooo long! hello again to all my OB friends, i hope there's still someone on here i know lol.

2 weeks ago i was my sister-in-law's support person and her labour went for about 30 hours. in that time, my partner had the kids for a full day and night which we've never done before.
my 13 month old daughter had started weaning herself and was down to 2-3 feeds a day before this, which i was absolutely rapt about, but after being away from me for so long and going without her feeds she's started feeding all the time! If i let her she'd feed pretty much all day, literally!!

is this normal?? should i just let it run it's course or do i need to take drastic action?

thanks, that's kind of what i've been doing. i live on the west coast of the south island, we're the rain capital so it hasn't been very hot here at all.

maybe i should just try and distract her for as long as i can when she starts pulling at my top.
