Just need some objective opinions please.
Have a much older sister and am taking my 2 small dc's to stay with her soon, just for a few days. We are going by train but are going to be using her car so I asked if she would mind if I bought 2 booster seats & had them delivered to her house. She wrote back saying there were some very cheap ones on a supermarket website and if they were ok she would order them for me. The ones she meant were the very basic, seat only £20 ones and I like my dc's to have the head protection too - these cost £50 each. I wrote explaining and saying I didn't expect her to pay for them, just wanted to know if it was okay to send them to her house. She wrote back saying she thought it was an awful lot of money but to go ahead if I wanted.
There is a ton of history, much too long to go into, but a lot of it is around me feeling judged and criticised, so am I just being over-sensitive in being upset at what I feel is her disapproval of me spending an extra £60 on car seats?
TIA
