Just turned one

My 12.5 month old is fighting me at naps .. 1st (around 9:45-10) one he will cry for 5-10 and sleeps max and hour. Use to be much longer .

2nd is a complete fail, it’s been 4 days. (around 3pm)

I know he is teething and dealing with separation anxiety but how long can this go on.

i am putting to bed at 6 now , before it was 7:30.
