When they are infants, go out. It gets harder when they get older.

Best advice I didn’t see anyone cover: prioritize sleep! Set schedules and keep them as much as possible. We started sleep training at 6m and I heard of people starting as soon as 3m. Search cry it out method. Kids need to learn how to self sooth. They can’t rely on stroller, car rides, MOM, being held in order to fall asleep. I’m not saying you should never do it, just limit it as they get older.

TL/DR version of Cry it Out. Send Mom away from home for the afternoon/evening and get ready…that baby wants you as you are EVERYTHING to them. Assuming they are well fed and diaper changed; put them down and get out of room. They cry, set a 5 min timer, go in settle them, check diaper, walk away. They cry set a 10 minute timer. Repeat but make sure you increase the time each time to you calm and check on them. 15, 20, 30, go in check on them and sooth them enough they aren’t hard crying. This process is hard on Moms, they are programmed to check on crying babies. I challenge anyone to cry for an hour and not be exhausted. They will fall asleep, it is a bit taxing but 2-3 nights and they will go down quicker and sleep better in the future.

Prioritize sleep! It pays dividends for the rest of their lives.
