Our 3.5 month old was able to sleep 5-7 hours a night with no problems, up until the last week or so. Lately he’s been really fighting going to bed when we try to swaddle, gently rock, give a pacifier, nurse and even use white noise (all of which were successful in the past.) But now it’s very challenging to get him to fall asleep at a decent hour. We noticed he would nap throughout the day so we tried having him take shorter naps earlier in the afternoon. But it’s been a struggle.

Is this normal? And if so... any tips?
