Ah well paci is personal preference and I don't think they are an issue! Hold onto it if it makes things easier for you too

soon she will get it! Sooner than later that's for sure! My first never took a paci and did the thumb but never caused problems. I think if they suck well into like 6+ years when their permanent teeth come in, it becomes an issue. He also only sucked for sleep- never during the day. My newest addition took to the paci and I didn't mind it UNTIL it became more of a prop for us during the 4mth regression. Either way is ok I feel. Just a matter of preference
Well many have said the first A time is normally on the shorter side since the first nap is more a restorative one.
I know I've been advised to start pushing the first yes, then if you get a long nap push the next a bit further than that first A time. For example... Our first A is 2.15 (which has now started giving me 45 UT naps) and if the nap is 1.5 or so, the next A time I'll push for asleep by 2.20/25 A time. It's worked. Since I've began pushing A times, if he happens to short nap one of them, he can still handle the 2.15 A time and give me a long nap for the next.
Pushing A times will be a struggle as they adjust, and I've realized some short naps may happen in the process and hard time getting down or fussy babies... But once they get it, your good! After a good week or so my LO is adjusting better and going down easier again. I see a lot of moms saying their babies can't handle being up any longer and are scared to get that push in (and end up just going back to the shorter A time/or put down sooner) but they need to or you end up in a ugly UT/OT cycle which I got myself with frustrating NWs (which have now stopped since)! ....if they get fussy, mine did best in my arms bouncing him around as I walked and did things-- or watching his hyper brother lol! The best thing that worked for him was taking him outside. Always calms him down immediately. It helped push those extra 10/15 mins

personally, I prefer a slightly OT baby with good naps or if short, can easily be resettled. Where as UT naps are rarely resettled and they end up getting OT anyway and it can get confusing, imo!
Hope that helps!
