1st time mom

Okay ladies, so I’m a 1st time mom and my little jelly bean is due in March. I’ll be 14 weeks tomorrow and I have questions. So I wanna take full advantage of things places offer for free to help with the baby. I don’t want that to sound greedy or anything..but I don’t see any one on my husbands side really bringing useful stuff for the baby at the shower unfortunately.. what are some places or websites I can sign up for free samples or stuff for the baby. I’ve grown up taking care of infants a lot of my life but being an actual mom for the first time I’m not 100% sure everything I need or don’t need so honestly anything helps.
