I swaddle our girl as the startle reflex wakes her up. This has helped
Mine does the same! I just lets her cry
My daughter is the same age and she’s also been fighting her sleep i’ve been either letting her contact nap or when you put them down keep a hand on their stomach until they startle and fall into a deeper sleep , it usually doesn’t take long but last night for me was hard I had to sit stroking down her nose for a while and play white noise 😅
My little boy is the same in the day but will settle more easily overnight
You're probably missing the window of opportunity to get her to sleep before she gets overtired. Look for early tired cues. My son makes sort of screechy noises and moves his head side when he's tired, usually around 45-60minutes after waking. If I rock him or put him in the sling at this point he falls asleep quickly and without crying x
Can you have them in a sling for naps, that way when they jump they don't wake themselves up
