it also has some to do with the position the baby is laying. way to make sure your baby is getting a lot of oxygen is to not cross your legs. if you sit on the ground make the butterfly pose with your legs. that way you arent cutting off blood flow to your legs.
- my son (6 weeks old)would get the hiccups a lot when I was pregnant and he gets the hiccups now when he gets to cold, so I just either give him milk or cover him up with blankets to make him warm again... and if you do skin to skin that helps too
My 10 month old had hiccups every time I would eat or drink anything the last 3 months up until she was 3 months old. Gripe water saved her. She hated hiccups. I think it says on the box they need to be a couple weeks old tho.
Well if it doesn't bother them it's actually super cute and usually doesn't last long... If it did upset them I would just nurse them and it would take of itself..
