I love breastfeeding my 15-month old, it's hilarious as he is fairly gymnastic while he feeds. So he'll be sort of climbing all over me while latched on, or just lying there feeding, kicking his legs ecstatically. Or I'll end up lying on my back and he'll be standing up, but sort of bent over in an upside-down L shape - he actually went back to sleep feeding like this this morning.
Also, sometimes when he really wants a feed and I get a boob out he does this really funny 'hur hur hur' deep kind of laugh of joy.
Oh, and my least favourite thing (but it's so funny!)- if I'm in the middle of getting dressed and I'm topless, if I ever bend down to pick him up he manages to latch on as I bend over, which means I have to hunch until he lets go! Very uncomfortable!
What was really great though was a few months ago when he had a D & V bug and we were told not to give him any food or milk or anything except water and rehydration tablet stuff - oh and breastmilk was fine too. I was really happy that I could breastfeed him, and I'm sure it helped him get over his illness quickly.
Oh, and if you go to the children's playarea at my local park and it's inexplicably full of late teenagers smoking and swearing, no amount of pointed looks will stop them, but breastfeeding on a bench will apparently make them pack up and leave within about 5 minutes.
