My brother and SIL are great with my kids and it's nice however, they have a tendency to over-step with my eldest.
They have done things like planning days out or particular activities for her birthday and speaking to her directly about it instead of me. I had planned the same thing but because they told her and I was keeping it a surprise I had to cancel. SIL said she used to always do this with her Mum (yes, so maybe consider that I, as her Mum may have wanted to do it)
Inviting her to spend the day on a specific day without asking me - again we had plans which I couldn't cancel so DD wasn't happy with me because I said no and it would need to be another day.
Buying things that aren't age appropriate. Expensive make up is one example, DD was 9 at the time and other than a teeny bit of blusher for a party etc she wasn't allowed to wear make up.
The latest is suggesting she could maybe join them on holiday - that is a flat no.
There are others but this is the basic gist of it. It's nice that they want to spend time with her and clearly adore her but I want to be consulted BEFORE they speak to DD because if it doesn't suit or I say no she just assumes it's me spoiling her fun. I also have 2 children and it's clear they favour the eldest but it has in the past upset my youngest (who has done nothing wrong, she's just 6 compared to her 11 year old sister so probably viewed as more work). She's felt left out at times so I've had to make some decisions based on that also.
I've asked they go through me but it's been ignored. I've told eldest DD that the holiday thing was probably just said in a "it would be fun way" rather than a plan but I actually think they are testing the water.
Am I being silly or do I need to tell them to back off a bit?
