Thomas Meltdown

Argh,
I just had the biggest toddler tantrum meltdown in the world.

Dropped Alice off to playgroup, wizzed round to Asda to grab some bits and pieces for the weekend (hopefully of a barbaque tomorrow) and saw Thomas had just dozzed off in the car.
Normally to wake him up is no problem and he is his usual merry self once he's in the trolly, but not today!

He screamed when I put him in, and was grumbling while we went into the shop, bumped into a friend and spent 2 minutes chatting, this was two minutes too long for Thomas though who deceided to start shrieking (that high pitched cry that sounds more like its indedned to attrackt wild dogs!) so I made my excuses and off up the aisles we went.
The noises didnt stop, I tried caliming him down, only to get slapping added to the problems, I tried telling him off, which increased the volume, I tried ignoring him for 10 minutes and then I tried feeding him the things I hadnt paid for yet!

None of the above seemed to work, and if anyone has any better ideas PLEASE tell me them!

We had only been 20 minutes when I deceided to give up, having a trolly full of purely junk we basically dont need from the attempts to grab things.
It got no better at the check out where taking him out the trolly for a cuddle only seemed to incite more slapping of mummy.
I was feeling like the lowest, scummiest mummy possible while the ladie infront of me deiced to chat to the checkout assistant for at least 2 minutes instead of paying, and I was about ready to burst into tears by the time my shopping was being scanned through.
I thought my order was surely over but no, the old lady returned and in her attempt to 'help' kept taking the shopping I had packed out of bags in my trolley and trying to pass them to Thomas, all this led to was double packing and double screaming, I sunk to new lows though by actually telling her she wasn't helping.

I now feel like the world worst mum, and am dreading the prospect of waking Thomas up in 10 minutes so we can pick Alice up.

2 coffees and a *aherm* packet of sweets later I am at least feeling calm(ish) again.

Lesson learnt, men hate shopping, avoid taking any age of male human shopping at all costs!
