There are lots of good brands. Having spent what feels like a lifetime buying plush toys for my kids and grandkids, though, I recommend a brand like Jellycat Toys UK. I think they tend to make very sturdy plush toys – which is more important than you think. You will never appreciate a plush toy being sturdy until your little one has ripped the arm off by being a little too rough!
My advice would be to look into Jellycat. They also tend to be very good at providing quite creative-looking plush toys. Other brands can feel a bit ‘by the numbers,’ but I have never really had that feeling about Jellycat. Definitely one of the better brands out there and absolutely worth checking out if you want something made to last. You cannot beat durability in plush toys, trust me!
