Spoiling yourself before baby

So ik once baby is here my money/finances will be mostly/solely spent on him or her🥹. But I’m feeling like I need to “spoil” myself for the next couple of months before baby gets here😫😭 I started today but I wanna buy all my clothes, shoes, bags, & perfumes. Have any mamas felt like this? Does it make me selfish?

Plus baby is due in my birthday month so ik for a fact I won’t have a “real” splurge on my bday for a while.
