Oh no, I feel myself being sucked in.
Won't read rest of thread, it will just set me off again.
I don't think any child is "too old" for a stroller. We parents may get too tired to push them around, but let's not kid ourselves that we kick them out of strollers for their benefit -- we do it for ours.
If Alliepathy's MIL wants to use a stroller, I can't see any harm in it. Tell your DD that it's only for use at Granny's house by Granny, if you don't want to use one at home, any more. No discussion or negotiation on it.
DD is 5 and still jumps in stroller when vacated by her little brother; I don't have a problem with it. The only person who calls DD "baby" for her stroller habit is 7yo DS -- he's jealous that he's not allowed in any more (he's too heavy, wears the wheels out).
We spend so much time in society berating parents for letting their children grow up too quickly, and the rest of the time telling our kids they should be more independent. That being a baby is "BAD".
Why TF is it "bad", can someone tell me?? You can't have it both ways; either you let your children grow up at their own pace or you give them the message that they should always be trying to be more mature, that depending on us parents and not wanting to cope on their own is "babyish" -- and therefore "BAD".
