Advice Appreciated

Asking for genuine advice, not nudges based on a desire to swoop up my collection.

I just found out that my fiancé is pregnant and we are expecting the baby around September ‘25. We are not in a tough spot financially but the news has made me start questioning my priorities. I’ve got a collection of 30+ pairs of lows and highs mostly in the 10.5 to 11 range. All really well kept and only really worn when the weather is nice. Only a few pairs are still DS. Ignore the non SBs.

I am already going to sell my two old trucks which I am very attached to in order to buy a more safe and reliable car. Am I a fool for considering to sell the collection for the same reasons? The money from the sale would likely just go directly toward the down payment.

Pics are outdated by a few years so the collection has grown quite a bit with some recent grails.
