Advice please

I have a 2 and half yr old beagle Female and a one year old son. She was the center of attention from the start as we had her at 3 weeks old. Over the time of having my son the attention for her has diminished and I’m becoming frustrated and emotional trying to balance the attention but my son is taking most of it. I feel so bad for her as walks have become almost nill. I feel at a loss with playing with her as she gets so excited and jumps all over you. Wants attention at every given second and I’m just feeling guilty. I also have a cat that longs for attention. Heart strings are pulled so tight😞 any advice is greatly appreciated
