Well recently he's been up since about 5-5.30 and BT is at 7pm so that's a 13.5-14 hr day with approx. 1.5 hr nap. I started capping naps at 1.5 hrs many months ago to help stretch mornings and something worked back then. Think you're right though I will have to wait until the tooth is through and then assess from there. Yesterday he just had a 20 min nap as we were en route home and he slept in the car but woke when we got home and wouldn't resettle. Then tried early BT at 6.30 as he was shattered. Alas a 4am wake up. Its exhausting. Today he slept for 2.5 hrs- its so hard to shorten the nap when he's been up since 4am and I know hes shattered, just trying to avoid being too overtired. Its so hard, chicken or the egg situation.....
