I have children start just before they turn 1 year old who drop their morning naps quickly because we have busy mornings but I make sure I serve lunch shortly after 11 and get them into beds for naps shortly after 12. Small babies can't stay awake that long. As they grow I gently nudge things back to later times.

Right now I have a 14 month old baby who sometimes naps in the stroller for 15 minutes or so as we return from parks or other outings and she still goes to bed for afternoon naptime well, but otherwise she doesn't have a morning nap.

Experiment!

I don't tell parents when to stop their children from having bottles, that's their decision in my opinion and I do as they ask. But I might point out that another child the same age has been done bottles for a while or put out other such hints.
