I give morning nap till it starts to affect the aft nap. I start by shortening the nap to only 30 mins and then keep moving it earlier in the morning. When that 30 mins starts affecting the aft nap it's gone...... Every child is different .... I have one that still naps periodically in the am and he's 15 months and I have another that started with me in nov at 10 months and we took it away instantly
