Ds1 is 3.3 and is absolutely TERRIFIED of balloons. It's been getting worse over the last few months, started with him being scared of a couple of balloons popping at the playgroup Christmas party, got worse with each b'day party he went to over the xmas period (all his friends were born Dec/Jan) and by the time we went to the last one at the end of Jan I had to take him home early because he became absolutely hysterical when one popped.
He's now got to the point where he starts crying and screaming if he so much as sees one. We tried to go to Bella Italia for tea tonight (huge traffic jam, couldn't get home after popping out for 1/2 an hour, HAD to eat!) and he started screaming as soon as we got through the door so we left. So we took him into Frankie & Benny's instead and managed to get to our table before he started shrieking. We then spent the whole meal trying to keep him calm, with limited success - the other diners LOVED us, I could tell - but it was a nightmare.
So, any tips or tried and tested methods for getting him over it? He's never going to be able to go anywhere soon. I've tried reassuring him that they can't hurt him, got cross, but the more he realises they may pop the worse he gets. DH is suggesting putting him in a room full of balloons and popping them all to desensitise him (I think he's joking!) but any other suggestions are welcome!
