It's good that you asked the question, OP, because people have now highlighted to use only non-bio products on your baby's clothes, and you presumably wouldn't have known otherwise.
Having said that, (I realise this is contradictory), I don't know what's become of Mumsnet and our collective psyche, when we have to ask strangers for advice on e.g. when to wash baby clothes.
PP is right, and wasn't unreasonable to point out that you 're going to be a parent soon, and will have to get used to making decisions.
Trust your own judgement on simple things. When you're feeling anxious about making a decision, ask yourself: if I get it wrong, what's the worst that can happen?
If it's something simple, that won't actually harm the baby, try and make that decision yourself. If it's something with potentially serious consequences, seek advice if you aren't confident to make the decision yourself.
If you stop and try and assess the question / worry itself, you might be able to rationalise that you are perfectly capable of making decisions yourself, or that you need advice.
Maybe keep an eye on your anxiety levels, and if you feel them spiralling, speak to your midwife, or health visitor if it's after the birth, and you have been discharged from the midwifery services.
Good luck.
Everything can seem overwhelming at times, bur don't always assume that you are incapable of deciding what's best for your baby.
