Homeland question

Its a urban fiction book. My sister and I only remember bits and pieces of it.

A guy was messing around a women, and I believed he was still with his guy but didnt want to be with her (the baby momma) no more and the two women was friends. Any fast forward they ended things and he start dating the other friend, she gets pregnant. The woman has the baby, while at the hospital the other baby momma tries to kidnapped the baby, which alerts the hospital security and alarms and everything goes off. Well she gets scare and accidently drops the baby on the ground(lucky the baby the fine and healthy)

Another part is the other baby momma had a baby too, where the dude would get the baby and everytime he sit the baby up in the swinger the baby would lean over, which later they find out she was drinking throughout her pregnancy and I believed the baby wasnt his.

Another part is the baby momma had an older son who she neglected and while she was paralyzed or in the wheelchair for some reason(I cant remember why she was in a wheelchair) but anyways she was in the wheelchair and her sone purposely pushed her down the stairs while in it

Like thats all we could remember, like I dont even remember anything else as it was soo long ago

Please help if possible

Thank you
