I loved the Minion Fizz
, and glad to hear B is over the croup.
Well done on the potty training M and Nom
My two have been completely different with potty training, so I don't have a method as such, but my tips would be. Clear a few days in your diary to start it, buy some pants/knickers ready for training, spend a decent amount of money on a potty/toilet seat - make sure it is sturdy and comfortable, on the first few days you have to be on it 'do you need a wee?' every 10 mins or so, have a cushion that you can punch/bang your head against when you have to clean up yet another puddle!, it will probably be one step forward two steps back - that is normal!
Off to a coffee morning this morning, hopefully it should be two hours of respite from the boys winding each other up 
Oh, and ds3 can now get out of his cot . It may be time to convert it to a bed. Ds2 was reluctant to have his bars taken off just before his 4th birthday, so it's all new territory to me.
