16 week old naps

[Babybaby1982]

Hi all, I'm having a problem getting my 16 week old to sleep in the day. He's always been a baby who needs help to switch off and sleep but the past few days he has suddenly started to really fight naps. I could always cuddle him to sleep quite easily, using a dummy but now he either struggles in my arms or just sits sucking his dummy, doesn't even get drowsy. I'm aware of his awake times and have played around with different times but it's made no difference. He will sometimes sleep in the buggy/car but I wonder why he's suddenly started not napping at home. I wondered if it could be 4 month sleep regression although night sleep (touch wood) hasn't changed. I just don't know what I should be doing, I can get some naps in the car or buggy but this isn't always practical and I'd like him to nap at home too. He gets very over tired and definitely needs the sleep. Any ideas or experience of this? Thanks.

My little one started to do this, I found that a warm bottle, closing the curtains a a little rocking sorted her, I turned my livin room into nap zone, tue tv down, soft blanket n rocking .. She only has 2/3 naps a day of half hour tho x

A dark room, feed and rocking chair sometimes send him off, often wakes if I try to put him down though. I feel like I spend all day trying to get him to sleep..! Hopefully this is just a phase..

Have u tryed swaddling baby when rocking, so when he finally goes to sleep and put him down he feels secured x

Yes we have always used a swaddle or wrapped him in a blanket. It worked well up until about a week ago when he suddenly started refusing naps - I've spent the best part of today trying to get him to sleep and ended up with 2 x 20 mins whilst I'm holding him...at a loss at what to try next or just to go with the flow and not try to get him to sleep, just see what happens?
