Im scared...

I know my husband and i wanted our 2nd baby. Im almost 6 weeks in 2 days...but lately..ive been feeling worried and scared.... i dont want my 2 yr old son to ever feel neglected once the baby is here... i dont want him to feel i love him less...because i will never ever run out of love for him and his sister or brother. im scared...i cant help it..im just emotional right now..
