the one where my dd then aged 2 years and 9 months was a bridesmaid for my Ex Best Friend. The bride had limited experience of small children and was really quite impatient with her over a few things. Such as not letting her go to the toilet after the ceremony because she wanted to get straight on with the photos and then taking over an hour having also disappeared off to have some more photos done in the park, with my DD and her much older (in her 20s) bridesmaid, no car seat provided for my DD just a normal seatbelt slung halfway across her neck. Poor DD had only been toilet trained for a couple of months, how she managed to hang on and wait for the best part of nearly 2 hrs I don't know, but she somehow managed not to have an accident.
Same bride complained when I changed DD out of her bridesmaids dress for the evening do into something more comfortable and insisted she put her dress back on (she just wanted to play with the other kids there by that stage and kept tripping over in her long dress which she had spent all day in already), and grumbled again when DD finally flaked out and fell asleep at around 9pm (several hours after her normal bedtime), as she wanted to show her off in her dress to all the guests who had only come for the evening do. DD had been good as gold all day (surprising as she could be a mischief) and had behaved herself, but I was not about to wake her as suggested so that she could be paraded around whilst exhausted - that wasn't part of the bridesmaid deal.
Same bride asked me to style my DD's hair a certain way (think multiple complicated French braids and ringlets) which I did. A couple of hours before the wedding she called me and asked me to go to her house (I lived on same street) and do the other bridesmaid's hair in the same style- which I did and it took me about 50 mins. She then said that her own hair wasn't going right, would I mind doing hers too? CF wanted to save money by not paying for a hairdresser, now I wouldn't have minded if asked in advance, but this was an hour before the wedding. All whilst trying to supervise my 2 year old and keep her out from under the feet of the bride, and MOB and I was still in jeans and tee shirt at this point. I had fifteen mins to dash home, and fling my outfit on, had to forgo my shower, run a brush through my hair and chuck on some make up. Bearing in mind that I had been up since the crack of dawn making food for her buffet, which was all home made from various family and friends as they didn't want to pay for caterers (they weren't struggling financially, just very tight). (Ex) Husband and I pulled up at the church at the same time as the bridal car, and met them in the foyer. She then had the cheek to complain that we were late!! We sprinted into the church ahead of them just as the bridal march started up.
Not friends any more, not to do with the wedding but because she was a selfish twat and I eventually came to realise this and cut contact with her when I moved away.
