Soon to be mom of two😁😏😵😳😬

Okay so I have a son who will turn 3 years old just 4 months after my newest addition is born! I have been having crazy anxiety about having two children and the new responsibilities that come along with having two babies especially since they will both be under 5! Is this normal? Anyother moms on here have bad anxiety before having their second child? Any advice on how to cope? I think it might be rooting form me being an only child?? Pic to attention
