When you say "fussing at the breast"....

Maybe he is being nosy? I remember both of my kidlets getting really easily distracted while feeding, around that age.
Other idea that springs to mind is teeth. Sometimes when they have teeth brewing it hurts for them to suck. Although if he's not unhappy it probably isn't that.
Are you giving him his milk before solids? And milk before water?
Or maybe he is ready to drop a feed?

Sorry if I'm not much help, just throwing out every idea that springs to mind!
Good luck!

when ella self weaned at 6 months or so she simply refused the breast and totally ignored it. Sounds like he might be "fussing" and maybe too much is going on around him...try going somewhere where there are no distractions for a few feeds and see if that helps?

Sounds like hes just interested at other things. Quite a lot of the time if you introduce formula they realise bottles are way less work so prefer them and so start refusing mum. If you really want to hold onto these feeds and up your supply its totally do-able.

Is this a situation where marmite on the nipples might work?

my man has always been like that.......the nosiest little blitter you ever did see........and then he laughes especially if he knows your somewhere where someone just might see your boob........but he was also teething since 2mnths and he finally got them through at 8mnths phew..........i am still BF but have no got reallllllllllllllly good at him pulling away and when to hide :)

what exactly does marmite do? i hear alot of old wifes tales and have tried them but most of them are just that tales........my boy luves marmite especially on cruskits but wat does it do when your feeding?

I noticed if he has just woken up and is still a bit dopey he feeds better. Thats probably why he feeds so well in the middle of the night.

wow how cool.............sorry i dont get out much......my boy eats heaps but i would be interested to try this.......just for experiement and i really have nothing better to do :)

Ella started to get really fussy while feeding around 4-5 months and refusing feeds and I was really worried that she was going to wean herself, but in the last 3 weeks has come right around and she is feeding really well (I think it may in part be because she has started to become a lot more clingier and wants the cuddles assorted with feeding)

To try and get her to feed I always feed her in her room (away from other distractions) with the curtains closed. Or if we are at someone else house I go and feed in another room (otherwise she is far too nosey)
