My LO doesn’t like anything new

My husband and I love to shower her with new toys and things around the house and she doesn’t really like them or take notice of them.

She’s 4 months old. She doesn’t like her new swing or her jumperoo or any of the new plush toys or teethers or rattles we get her.

She is ok in her rocker for up to 15mins and then she wants out, and there are literally 2-3 toys she will play with a little.

It’s so difficult to entertain her and also frustrating because we have already spent so much money on things we’ve bought for her.

Will she like them eventually? Is it just a phase?
