I also put the hipseater above at my 肚腩, too. I feel the force is transferred from the hipseater to my hip bone which is good and not tiring.
I used it when I go to Cheung Chau and Lamma Island. I found it very handy as my baby could get down to walk easily (compare with carrier) and it saved the hassle of carrying a stroller up and down the steps. The only problem was when she felt asleep. The hipseater cannot help you much if the baby is sleeping.
我D飛係工聯會買,都係特價。咁就要補返差額。Eg.特價飛$205。佢要我補$45先可當$250減annual pass費用。Which means actually no need to buy 特價飛 if you plan to buy annual pass using that promotion.
