Daughter 4 years old very jealous of friends/family birthdays

[Anca123456]

Hello,
My daughter is in Reception and will be 5 in May. Since she was 3 she has been very aware and obsessed with her birthday. We didn't do anything special, it was just the 3 of us and we would go on a trip as it falls on a bank holiday weekend. She is not into gifts, just likes having a cake and candles ... and being important I guess. Her first party was at 4 when we invited her nursery friends.
Now she is asking every day when is her birthday and why it can't be sooner. She doesn't want to go to her friends birthday parties or if she goes she won't sing Happy Birthday. She talks about her birthday every day, just drives me crazy! And she cries because she want it to be now. I've told her we could have a cake and celebrate that she is 4 years and 9 months old but now she says it's no fun without her friends. She has a difficult personality to put it nicely :D and is extremely stubborn.
Any suggestions on how to stop this birthday obsession/jealousy?

My 4YO went through this a few months ago. I will answer the question about when her birthday is once but then I simply tell her that she knows when it is and we are not going to talk about it any more. It took a few weeks and some histrionics but she’s back to a ‘normal’ level of thought/questioning over her birthday now. It was about presents with my DD though because she’s the same if she knows she’s got something coming in the post.

I do think they go through phases of fixating on something at this age and a big part of it is that they still don’t really understand the passage of time.
