Second baby shower?

I'm pregnant with my third child, my second girl and with my son I had the worst baby shower, we had it at my mum's house and when I arrived a hour before it started there was no decorations and barely any food and the only thing my mum had setted up was the two tables and some balloons and my sister came and said she was making fairy bread but had no money for bread which is $1 and she has a full time job and two children so I had to send her to the shop to get bread snack food and drinks because they literly had nothing and had a whole 10 weeks to prepare :( it really devastated me because they were in a better financial situation then I was at the time and it was just a nightmare..

My mum feels absolutely horrible and wants to throw me one at my house and pay for everything and make it the best day ever but I have never heard of anyone having another baby shower I thought you only have one for one child :( I don't know what to do any advice is appreciated
