How can I make my yoghurt smoother and less 'bumpy'??

[TelephoneTree]

Kids won't eat it - say it tastes nice but they don't like the texture!

They are used to eating the yeo valley natural yoghurt and this homemade stuff is a bit more like a set yoghurt i think.

Any thoughts??

I just give mine a quick whisk and that makes it nice and smooth. The other alternative is to strain it to get thicker texture more like Greek yoghurt.
