When should I start buying for baby?

Blanca

I'm 10 weeks 5 days today, first pregnancy. I haven't bought anything yet. I'm holding off because I haven't had an ultrasound yet or heard baby's heartbeat, so as weird as it sounds I don't want to jinx anything.

When would you all recommend I start to think about what baby will need and start buying? Is it reasonable to wait until the third trimester, or at least halfway through the second?

Or will I regret that and get stressed later on?

Any tips for buying for baby?

Thanks in advance!
