A 35 week old baby that is still in the mother's womb should weigh at least 5 lbs and be nearly full term or may be full term.
A baby is usually full term completely when the baby is 36 weeks old in the womb which is 9 months of pregnancy.
At 36 weeks the baby is around 5.78 lbs in weight and around 18.66 inches in length.
Some babies are born at 35 weeks and some of those babies do just fine and are healthy babies.
However some babies born at 35 weeks may need to be in the NICU for awhile to make sure they are gonna be healthy and breathe properly.
If possible it's best to have the baby at 36 weeks and not at 35 weeks.
But that is usually out of the mother's or doctors control.
