Buying baby essential at what month

This is my first pregnancy, im currently 22 weeks. I’ll be gg JB on my 23/24th week to recee some baby car seat, stroller, baby carrier, etc, like those big expensive items. Also planning to go baby fairs. Do you think its too early for me to buy those stuff during 6 months ? 😅 as i scared i wont have the energy @ 3rd trimester. But at the same time im always overthinking like what if i buy too early and touch wood something happen to my pregnancy 😣 What do you mummies think. When did you start buying baby items and is it too early if i start buying at 23 weeks or 6 months #firstbaby
