We have the same issues over here too. DS has been at 2hrs 45 mins for the past week as 2hrs 30 mins was all of a sudden getting us only 45 min naps. Now, I think he needs another stretch in A time which is unbelievable to me because he's only 5 1/2 months, but this morning he did 1hr 15 min morning nap and I can't figure out if it's OT or UT. Woke grumpy so I'm thinking OT, but he did the same amount of A time yesterday and slept 2hrs 30 mins. There are NO tired signs ever! Grrrr....
There is no chance of nap extension here anymore either. Starting refusing his paci two weeks ago and just won't take it anymore. Cries hysterically when I try to rock him or soothe him back to sleep. I'm worried my neighbours will call child services on me so I have no choice except to get him up. Of course, he's super happy as soon as he's out of his room.
Someone tell me this will be over soon....
BTW, Elise I remember when my DD was a baby, we had our furnace replaced one evening when she was sleeping. It was soooo loud, banging, welding, drilling, etc. She slept right through it. She also slept through the fire alarm going off in the middle of the night, the Angel Care monitor going off and the chain sawing every afternoon when the guy next door would cut his lumber for firewood. She's now 4 1/2 and the other day DH wanted to wake her up from her afternoon nap so he went in to her room and vacuumed it while she was sleeping. She slept through it!!! Of course, this is the daughter of a man who could sleep through a hurricane and not wake up.
