@LittleBlueBag As a fellow mum of twin toddlers with delays due to premature birth and for mine, low birth weight I salute you for going out in public at all! I think you've had the worst of MN today and I'm sorry for that. Truth is for a lot of people unless they've been in your shoes they find it difficult to comprehend how difficult it is to have twins with speech and developmental delays.
Mine are fantastic, so well behaved most of the time and so loving. But that doesn't mean they're above exploring the world in a way that suits their developmental level. I ask those who haven't had prem babies to imagine a child with the physical capabilities of a toddler but the mental abilities are behind. That doesn't make them stupid and eventually they do catch up, mine are half and half, DS is extremely behind on language development but doing well in catching up physically, DD is ahead on her mental development but behind physically.
As such, when my DS who is such a lovely boy, has a meltdown in public I have to comfort him and speak to him in the way that works for him, by cuddling and holding firm until his tantrum calms down and then cuddling him gently and rocking him. I've had some nasty comments from perfect strangers who simply do not know what it's like.
OP has said her toddlers were on reigns but she had to turn her back for a fraction of a second to pay. In that time they had their hands on/in stuff, I'm sure she reprimanded them, but if they can't comprehend the instructions she has given at this point, what more could she do? Strap them into a buggy so they scream in frustration and she gets side eye from folks for twins who are desperate to roam screaming their lungs out? Keep herself and her children indoors because it might inconvenience others if they play up a bit? Seriously, this thread (bar a few decent posters) has been absolutely atrocious and certainly not the support that mothers should be offering one another. SMH
