I would highly suggest avoiding it completely. After my loss, we became so careful about everything. Even husband's lifestyle matters a lot, please ask him to pause drinking for safety.
Uff, my husband had to give up his weekend beer when we were trying. Honestly, once the baby comes anyway nobody gets time to sleep or drink, so tell him to start practicing healthy life from now itself!
Haha if we have to leave our favorite pani puri and spicy food, they can also leave their drinks na! But seriously, reducing alcohol helps a lot in conceiving. Let him enjoy mocktails and good food with you instead!
Direct answer is yes, he should limit it. Mere husband completely quit set done did when we were planning. It actually helps in getting a healthy pregnancy faster, trust me.
Honestly, it is always better if he limits it or stops it completely for a few months. Sperm health improve hone me time lagta hai, so thoda sacrifice is good. Ask him to focus on healthy food and exercise too.
