Trollies with baby seats

The last few times I shopped at PnP Clearwater mall I could not find trollies with baby seats. I mostly shop in the evenings before the store closes. Does PnP put them away perhaps? Please can they be available in future. My baby doesn't like sitting in his pram since he wants to see me. The trolley with baby seats are much better for me. Please can this issue be addressed? The last few times I had to let him sit in the trolley and he's too small for that. He keeps falling over. Thanks
