Happy belated new year ladies 
I have been chortling over your autocorrects Fizz. My favourite being tarts on the bedding. I guessed it as stars s we have the same!
Lovely to hear from you Cycle and congratulations on the bfp 
Ds3 can get very physical. Mostly with ds2 and us, aren't we the lucky ones. I tend to tell him off, take him away from the situation and leave it at that. He doesn't always understand why he behaves like he does, but I do make sure that he knows it isn't acceptable.
I say just go for it with potty training. Expect wet pants, expect puddles on the carpets, expect poo's in the pants, expect regression after you think you've cracked it. All of these scenarios are pretty much inevitable at some point, so just roll with it, it's part of it and character building!
School for both boys tomorrow, and from this week onwards ds3 will be doing 3 sessions at pre school - woohoo!
