Hope you don't mind my posting here

Our close friends told us today they are expecting their first baby, YAY! So, during our girl talk friend tells me they had been trying for 3 years and needed assisted conception due to PCOS I am so happy for them and I really want to get themsomething special and not overly generic. Do you have any ideas of something we can give them? I know they'll be getting tonnes of stuff, but considering their journey I thought they'd really love a meaningful gift, not just another onesie
