Idk like at the end of the day no child is going to have every single toy they want at home so I don’t feel any way about the aesthetic boundaries stuff tbh lol. Kids get to play with such a breadth of toys through play groups/nursery/play dates/cousins etc but still go back to what they have and remain untraumatised? Kids have to be told no and suffer disappointment whether it’s over a horrific pink barbie private jet or ice cream for breakfast. They’re evidently not deprived of toys or adult led play
I love the gift boundary stuff though and have used it, in our situation it benefitted the gifter who felt a huge pressure to go OTT (she’s a superstar auntie who is the love of my LO’s life), it meant we were both really happy with the compromise we discussed and I don’t have to deal with a new 56 piece Duplo set entering our home twice a year! Appreciate it may be more awkward for acquaintance level friends or super extended family if those ppl buy for your family.
