Did you have to put some effort into it or did they just use it from the off?
My 5 month old is out of the swaddle and will now only nap in his cot if I gently hold his arms down until he's asleep. He does take a dummy but he knocks it out if his hands are free hence the arm holding. I can't do this forever though because he'll be in the big cot soon. I give him a comforter in each hand hoping that will distract his hands so he won't knock his dummy out if I let go of them. Now, if I let go of his hands he will grab the comforter and start stroking his face with it, good! But doing that seems to wake him up if he was getting drowsy, and makes him more energetic! How does the comforter go from being a distracting toy to being something that helps them sleep?
He's EBF and I feed him to sleep and DH transfers him to the cot at night, but I'm shit at transferring him so I need a way for him to nap in there in the day so I can be with my older one.
