Thanks you for the reply. I will post somewhere else.
Just a couple of questions regarding the top-offs:
1) she seems to be fine with top offs during the last two days, but she was waking up in the middle of the night for a cot party around 4am. I'm not sure if this is a top off issue or just teething issue because I was actually giving her Tylenol around 12am and it says that Tylenol lasts for 4 hours. Just wanted to check.
My friend also said she had these 4am cot parties when she had a long A time in the morning and late naps. She limitted the first A time by 2-2.5 hours and these issue went away.
2) today I gave her top off in the morning and she only fell asleep after 4 hours and 20 minutes of awake time. It felt like this top off recharged her and she couldn't go to sleep (even though she showed the sleepy signs). Moreover she slept only 35 minutes after such a long awake time.
