IKEA

Changing Area/Feeding Room: Yes. There's a little room just outside the cafe next to the ladies toilet. Clean and comfortable. It's sort of a display-cum-use area. Much like the rest of their store. It's excellent. There are two changing tables side by side with their blow up white changing pad. On top of that are rolls of paper that you can lay down on the changing pad in case you don't find it clean enough or you need to wipe anything. Then there are hanging mobiles. Lovely! Great to distract baby for a while until you can pop them back in their diapers/nappies. There's an armchair that fairly comfortable in the corner for breastfeeding moms. The place is really just big enough for one mom and baby (maybe a couple of older kids at the most). I like that it's big enough to push your trolley in if need be. There's a lock on the door if you really need privacy.
Babyfriendly Trolleys: Yes. On Level one where the displays rooms are, there are small trolleys that you hang those yellow bags on with a little seat for the babe. The trolleys are light and easy to maneuver. The walkways are wide and gives good space for the pushing the fairly compact trolley around. Then if necessary, going up the little ramp into the side displays are not too much of a problem - just a little slightly harder push up. The trolleys aren't all that stable though, so be sure to keep a close eye on baby. Especially wriggly climby wormy ones. That said, however, Cerys and I had some fun times wheeling around in one of those.
Play Area: Smaland. Excellent for kids above 3 years old. They check kids in and then you can collect your kids on your way out. Kinda like Kizsports but I don't yet know if you need to pay. Will find out next visit. Then there are various play stops all over the complex for kids to play with! Cerys at about 8 months was crawling and loved the slide - with lots of loving help from Papa of course.
Family Parking Bay: These are the best parking bays in Malaysia! And their family parking bays are so so spacious. Only problem is, they all seem to be always taken up! Sometimes walking past, I don't notice any baby/child seats! So it either means they don't use car seats for their babies/kids or they're just plain insensitive.
Extras: IKEA is wonderful! A tired mom can sit just about anywhere in here! And plonk themselves on some very comfortable settees on the pretense of trying them out! When really, we just need a some time off our feet for a bit. Or maybe sneak a sip or two for the little one.

I'll update with photos for this one soon! :)
