Carol: Yes, i did put toys, books & "high chair" (those type that you attached to a normal adult chair) at nanny's place. No walker (those sit-in type) since I do not want my boy to use it. When i used to rent jumperoo & exersaucers, i also got them delivered to the nanny's house since he spent more time there. Other stuff i put there: mattress, playpen & essentials like clothes, towels, diapers, bottles, plates, spoon, pillows, food, etc. Best to check with your nanny what she can provide and what you have to provide.
SK: I bought from Luvbabies before. Source should be safe coz packaging looks exactly like those that you buy from supermarkets, at least for Nan HA. They are actually the "online division" of a medical hall in Jurong (yeah, medical halls also caught up with online shopping trend)...so they do have a brick & mortar shop though i've not been there before...too far for me lar...if u stay in the west, perhaps visit their shop and have a look? =)
