I've done this many times to several infants in my care and never have they remembered anything later on and never were they crying or in a bad mood afterwards. If they start to get a bit fussy just blow on their stomach or back off on their pussy because you may be irritating them. Just wait an hour and come back when they are more relaxed
Obviously they would taste best fresh out the bath. It isn't for many but I like to rim her asshole a bit after sucking on her baby lips for a bit. You can cum [IN] and [ON] them as much as you like. A quick wipe with a wet wipe is all that you need and babies are often sticky from their own saliva/drool that more often than not nobody can tell you just came on them
I have no experience with penetration so can't give any advice in that regard. I'm into it but know that they are too young for that shit and I can't force my dick into a crying baby no matter how horny I get
Other than jerking off and rubbing your dick on their bodies - I find most like to lick a lot. So as someone above stated just put your dick near their mouths and they will quickly start licking. I wouldn't suggest giving a baby a facial but milking the last drop of cum onto their mouths doesn't hurt them in the slightest
Good luck man. I hope you get to experience everything about her and finally realize why we pedos just love little girls. THIS is the way they are supposed to be experienced. They were born to please us
