feeling really guilty

So my mum who is absolutely amazing bought me a beautiful cot set so blanket, sheets, bumpers all that and it is very nice..but it doesn't match the theme I was going for in the nursery..I know super childish and petty but it's my first baby first time decorating a nursery and I want it to be perfect and I know she is gunna want to see it on display all the time but I really don't think the OCD side of me will want to have it on the cot like I will definitely use it..just not all the time and I'm worried she might get offended ughhh 🤦🏼‍♂️ I'm so annoyed that this is even bugging me because I like the set it's purely that it doesn't fit my theme that is annoying me and that it's not some distant relatives gift that probably won't be coming over to visit every other day.. anywho just needed to vent
