Need advice please

We will be going on a trip in a couple of weeks, and my morning sickness is extremely terrible this time round. My puke comes out suddenly, can’t even be controlled. Plus I have a toddler who sticks to me like a 3M sticker. Can any mummies here give me any tips for the follow (I told my gynae not to give me the anti-nausea pills because I’m avoiding medication if it’s not life-threatening medical condition): 1) any natural remedies for nausea, especially on plane? 2) how to handle vomiting with a toddler next to me? (My toddler ran after me a few times when I rushed to toilet to puke and kept asking me if I’m ok. I feel so bad for my toddler to let him see me so distressed & sick) 3) my toddler needs me to wear him and rock him to sleep whenever we are overseas, if not he won’t nap as he’s having too much fun and won’t wind down on his own, unless I lock him in my carrier and rock him to sleep. Toddler is currently 16kg. Should I still wear him this trip, or are there are ways to get him to sleep? I’m in my late 30s, so I find myself more exhausted and my body is aching badly even though I’m only around week 6 now. I appreciate all your kind advice and feedback. Appreciate if mummies could keep any bashing to yourselves for now. Thank you 🙏
