3 new infants started 3 weeks ago and all of them were having 2 naps at home. I already weaned one of the first nap and one of the other 2 did not slept during the morning today, he just laid down quietly. I just reduced the time of the 1st morning nap gradually. You could gradually wean the guys that are coming earlier but it may take more time. At least with shorter naps in the morning for a while you will have more time to get things done.
