Belly band pros and cons

Rebecca✨ • 29,FTM to my 2 year old daughter && coffee-obsessed!

Trying to decide if I want to buy a belly band so I can still wear my pre-pregnancy jeans or if I just want to invest in a few maternity jeans/pants. I'm a nanny so I'll be chasing after two kids and I'm just worried that if I went with the band that I would be constantly adjusting it?
