How is B today Fizz? On the mend I hope.
I don't know much about formula Kitty, but I am led to believe that the comfort formulas are a load of old guff/ clever marketing.
Ds3 has been a right flipping handful at the moment - very wilful. My patience has been tested to its limit. Lots of spitting - not at people or in anger, but spitting nonetheless.
Today was the start of the pre school term for ds2, so I thought we would all start walking there, ie no buggy for ds3. It's a short walk and easily manageable for him. The walk there was fine, enjoyable almost. The walk back took 30 minutes (it should take 10 max at ds3 pace.)
He protested about leaving the pre school -fine, I can understand that. He wouldn't let me hold his hand. He then sat down on the path and refused to budge - even when I said bye and walked out of view. When he decided he was feeling in a better mood, he got up and started walking - but backwards. Backwards?!?! He walked backwards all the way home 
Luckily the day got better. We had a great time at toddler group and the walk to and from pre school pick up went well. No doubt because ds2 was there.
He can't start pre school until September. That's months of having to forcibly remove him from the building 4 days a week.
