Bending over to tie your shoes properly is safe and will not hurt the baby. But you might feel uncomfortable and out of breath by the time you’re done. Even if there are plenty of footwear types, shoes are the safest option for a pregnant woman. So, if you need to tie your shoes during your third trimester, it is better to ask for help for your comfort. Of course, it won’t hurt the baby; it just saves you some struggle.
