I had five kids. Each child was a different situation. Your best bet is to either “Ferberize” them, the method of going out, saying good night, and letting them cry for a few minutes, then coming back to reassure them that you are there and they should go to sleep, let them cry for a longer period, come back, etc, etc. OR you can simply allow the baby to cry (by three months, they are certainly old enough to go through this, as uncomfortable for you as this will be, but it will only be for a few days. Get ear plugs or the headset from a radio.
