Ask HN: What are typical maternity leave conditions for US seed startups?

I am a startup founder and a father of an 18-month old daughter from France. We are based in Paris, but are planning to open an office in the US and are considering conditions and benefits to provide to our team members in the US. In France, paid leave is 16 weeks for mothers and 28 days for fathers. Cost is mostly covered by the state, with a small part left to the employer. We are thinking about replicating something similar for our employees in the US (cost will be more significant than in France given that this will be 100%-employer covered). Conditions at big tech companies are well-known at around 3-4 months of paid leave, but I am wondering what is typical, the norm for US seed startups? Thank you for your help!
