Hi, so I have a 6 Month Old so & He hates tummy time. I can only get him to do about 5 Mins Max a day. He sits up by himself & can jump in a jumper & can even stand up while grabbing on to a surface. He doesn't roll much but I think it's because of the lack of tummy time.. so I was reading that generally a baby needs about 1-2 hours of tummy time in order for them to build up the strength to crawl around 8-9 months. Any thoughts or suggestions would be greatly appreciated !😊
