Help with product

Hello everyone I hope this is not against this group’s rules. I would need a little help if it is possible. I’m a small, new, home-based company and I’d like to sell great products for every mum and dad. Could you give me an idea what will be best for you:
If you wanted to buy a BATH TOY ORGANISER, what would you like as a free gift:
1. Bath toy (ex. duck ets)
2. Bamboo baby washcloth
3. Pacifier holder
4. Bib
5. Something else?
I would really appreciate your help.
Also If you are interested to test it, in the near future I will be giving a large discount (eg. 80% off) for the product in exchange for an honest review on Amazon. If you are interested, please send me a private message.
