It's hard not to have enough sleep.

Some ideas I have that may or may not help.
- Can you put him down earlier? During a stage of one of my boys resisting sleep-time, I found I was leaving it too late, and putting him down earlier before he had a chance to get his 'second wind' worked.
- I'm not great with routines, but some people swear by a routine so that when the same thing happens each night, bub gets used to learning to wind down. Dinner, bath, bottle/story, bed, whatever.
- Do you have a laptop? Or a good book/magazine, and a low light, and maybe you could just sit with bub as he tries to settle? You can reassure him that you're there, but maybe see if he's okay with you not picking him up? You could still lay a hand on him or pat him if needed. But you won't be bored, if you can get your partner to grab you a cuppa, it might feel like relaxing down time for you too!

Anyway. Take or leave them. Hope you and bub get some good sleep going. xo
