Ok So My Daughter Is 5 Months And Has Been

Ok so my daughter is 5 months and has been like fussy all day when I try to lay her down to sleep and just wakes up crying. She isn't anymore stuffy then usual and last time I took her to her ped. He said it was just a viral thing and she didn't need medicine. Her boogers are like dry and clear. She's still eating, peeing n pooping ok. She still plays and smiles and laughs and coos.But the past few nights only at night she's been having cold sweats and like tonight she choked drinking a bottle but like was breathing the whole time burped and formula came out and she's fine and sleeping now. But of course I googled baby with cold sweats with no fever and it said its linked to SIDS. But She is teething and I also saw its linked to that. And of course I'm like so freaked out and want to cry so I just wanted your opinion. I'm gonna call her ped. First thing in the am tho.
