As Jessmum said, yes it is common
especially during this time of various growth spurts.
I would try not to worry much. I know it's very frustrating and hard
I just passed that phase myself!
again....
....and sleep is so wonky those first few months. It will settle then get crazy again around the 4mo regression.
Is he bottle fed or breast? Sorry if you addressed this and I missed it
IRT the nap, yes! That's common! My LO did that. One nap is always longer. Naps begin to adjust as their A times slowly increase. The way I tried to see thing is 0-3 months they "work" on their night sleep... day and night confusion seems to settle, NWs do become less than those first every 2 hr wakes (for some)...etc. 3-6 I feel they work on their day time sleep
Many hugs. This all seems very common. Frustrating most certainly... hang in there mom
