Dropping to 1 nap

My little one refused his second one today and over the past 3 weeks has refused it here and there. He only naps for 50 mins in the morning so its not a long nap but where it isnt consistently being refused I dont know if he is ready or if maybe its his teeth

We tried 1 nap and 3 bottles yesterday as her first nap was 2 hours and she was up for 7 hours.....😅😅

It wont let me reply to your comment OP but yes, from waking her up for her nap in the afternoon she was awake till 10pm and was a tiny psycho, just wanting to play, wouldnt sit down, lie down or be rocked.
