Not safe. The problems are rare, but why risk it?
Your pillow won't smell like you much after the first day, anyhow, so it's unlikely that will work.
Lots of moms wrap the baby in a blanket while holding him falling asleep, so when the baby goes down, the blanket that smells of both of them goes with him. It helps some kids avoid the 'sheet allergy' of being put into a cooler, darker room on cold sheets.
That said, it's extremely unusual for babies to sleep through the night until they're well over 2 years of age, so you may be trying to solve what a friend calls 'a reality, not a problem.'
You can't solve reality, you can only deal with it. If it's normal, natural and healthy for kids to wake periodically through the night to make sure they're getting enough food, staying clean and dry, and not spending the night abandoned in the woods where the tigers will get them (1yos only have instincts, not sense), trying to get yours to stop being normal, natural and healthy so you can get a solid 8 hours of sleep is probably going to drive you crazy, while not actually working.
It has been my experience that parents who have children who 'always' sleep through the night from some incredibly young age are lying. Not intentionally...but convincingly. There is some award of honour given to parents who have the 'right' kind of babies, so when the child randomly sleeps through the night twice (because he's eaten enough for the past few days to grow and needs the extra rest to do it, or because he's coming down with something and his immune system is stressed out) the parents cling to the 'we did it, we're wonderful' thing, even in the face of the same child waking up periodically virtually every night after that for the next 2-3 years.
The number of wakings that don't count get really comical: she was teething, he had a late nap, he's coming down with/getting over a cold, he had a busier than normal day, he had a duller than normal day, she had a shot yesterday, she was freaked out by a dog today, she had an uncomfortable poo, there was a loud noise, we were up late, she had an early morning, his nap was longer than usual... but that's all fine because they 'don't count,' because she always otherwise has slept through the night since she was 4 minutes old.
Yeah.
Lots of kids stop waking their parents up in the night, and some parents just stop hearing their kids crying in the night, but kids wake up through the night just the same.
