In the post, user Sophie9090 explains that she feels “a little annoyed but I am unsure if I’m being unreasonable. Our son’s first birthday is early November, I was trying to plan a party with my family and my husbands (we both have big family’s).”

She goes on to say that after inviting all of her husband’s family, “they all said they couldn’t make it for different reasons,” explaining that they all live roughly an hour and 30 minutes away and “most of them don’t drive, however there are train services, and most of them would be able to car share.”

Revealing that her in-laws have never come to visit them, and her husband is upset, the user wrote: “I feel it’s so selfish and I just don’t want to make the effort to see them.”

However, a poll on the popular discussion site found that 67 percent of 651 Mumsnet users voted that Sophie9090 is being unreasonable.

A baby won’t remember their first birthday, but despite this, a 2016 survey by website BabyCenter.com found that 26 percent of parents report spending more than $500 on their baby’s first birthday.

Another survey by U.K. supermarket Asda discovered that by the time a person turns 21, their parents have spent $28,000 on their kids’ birthday parties.

Newsweek spoke to Joanna Stephens, founder of popular parenting blog She’s Your Friend, who said: “It sounds like the parents-in-law here are not being fair, especially if the OP is the one always traveling to see them. When you have young kids, it’s hard to travel, so family should make the effort if they want to be involved. It’s possible they all did have prior engagements on the day you chose, but most likely not.

“My suggestion for people who find themselves in this situation is to talk to the family members as a couple. It may not be a big deal to extended family but it is to the parents as a child will only turn one once, and it’s always nice for family to show interest. Depending on the dynamics of the relationship with in-laws, it’s only going to grow more resentment.”

User Commonhealthgames said: “They’re probably not as into you and your child as you’d like them to be. And it not right—but the sooner you adjust the less drama you’ll have in your marriage going forward and the more you’ll realize—it’s ok. I am speaking to my younger self here.”

User LydiaBennetsUglyBonnet commented: “I don’t get the big deal at all about 1st birthday parties and wouldn’t travel more than about 15 minutes for one TBH.”

User pd339 wrote: “No-one cares about your child as much as you do. You can’t force them to be interested. Move on.”

Newsweek was not able to verify the details of the case.
