It sounds like you had an easy time. Good for you. Many, many parents suffer hell with babies not sleeping and being upset. It seems a bit dismissive to just say “oh just do X and it’s all good”.
My point was basically, if both parents have daytime obligations necessary to support the family, it’s very logical that they try to get the baby to sleep in the night ASAP
In that regard, having babies sleep in your bed, or having babies that cry though the night and accepting that as natural is a luxury (or problem) some families cannot afford.
