I'm looking for some advice. My boy is 3.5 months and he has always been "a bad sleeper" (always up at least 4 times a night, hardly ever naps longer than 30-40 mins) but recently nap time has become more and more difficult. In the evening he settles fairly nicely after bath, change and a feed. When we try and put him down for a nap he gets really upset. This happens regardless of time, and even if we make sure we answer to his first sleep cues. He starts crying the moment he realises it's nap time (any cradling, shhh-ing, lullabies etc) and cries for ages. Most times he starts crying again once we put him down too. Sometimes I manage to feed him to sleep, but even that doesn't work for every nap.
Any advice? He doesn't take a dummy and has grown too big to swaddle. White noise makes little difference. We keep the room dim and quiet leading up to the nap. He naps when he's on his carrier, but he hates the pram and mobile naps don't really work for all the naps he needs.
