My first child who is four years old recently started showing jealousy behavior. Like my child who was once very independent is becoming dependent. Behaving like a toddler all over again. Crying spells over simple things. Lately she’s been attempting to hit my stomach (31weeks prego) in a playful manner. At first, I thought maybe she was doing it on accident. Until today, when she actually did it intentionally. Can I get some good advice? Please?
