MIL creeps me out

My MIL is a super nice lady, would do anything for anyone but she takes it TOO far. While my husband was deployed she was sending both of us care packages and I had a bit of a jealousy issue because she was sending my husband literally everything he needed and then some & I felt like she was trying to take care of him like he was still her little baby. Like if she's doing everything for you, what the hell do I send you? Ugh... Anyways I just found out that some of the things she was sending him was fucking baby toys. She sent him a damn rubber duck with an army uniform on, a wind up toy chicken & another toy that said for ages 4+, and little toy trucks. My husband is going to be 30 this year and his mom sends him baby toys! And he likes them & plays with them!!! Do I have a right to be kinda creeped out by this or what? Not sure how to feel about it.
