second hand smoke

Anyone here po mamsh na madalas makaamoy ng 2nd hand smoke. Idk pro i always try to protect the baby naman. Pag makakakita ako umiiwas ako miski naka mask naamoy ko prin ? or mnsan kala ko okay na tapos biglang maamoy ko hahanapin ko kung san galing yong once mo lang maamoy pro kung everyday naman natatakot nako para sa baby. I just lost a daughter 3 years ago sa congenital diaphragmatic hernia and now i am hoping and praying na this baby is for us na. Anyone here with same experience with 2nd hand smoke na naging okay naman mga babies nila pag labas? Please enlighten me. God bless?
