My unpopular opinion is that fireworks are stupid. They're nightmarish for many veterans, they pollute the air, they scare the shit out of pets, and they harm wildlife. There is no reason for them being in set off residential areas.
After giving birth, a woman's internal wounds take six months to heal, 12 months for physical recovery, two years for hormonal balance, and up to five years to rediscover her identity. Relationships frequently fail during this time due to a lack of understanding. Be kind and patient with new mothers; they are facing more challenges than it appears.
