Hi my DS is about 3 1/2 months old now and I am still working out when he is tired.

Sometimes they don't sleep because they have a little wind, and sometimes it's because they are just way overtired.

In the early days my Hug a Bub really helped me out. it's like a baby sling. Basically if you have some sort of carrier and you can wear your baby they end up feeling secure and their head is near your heart which is a comforting and familiar noise. plus if you walk around the house for a few minutes the motion puts them to sleep just like when they were on the inside. then you can sit down and put your feet up, eat your lunch, chat on belly belly
