So my 9 week old DD sleeps beautifully at night- she only wakes once or twice after we do the last feed and settle around 6:30-7pm. If she wakes in the night she self settles or if she's hungry she lets me know, I feed her back to sleep and all is good.

Daytime however is another story. We do a loose freed play sleep routine but she will not only never self settle but she always screams before falling asleep exhausted. This is not grizzling or even loud crying but literally screaming hysterically for 10 to 20 minutes until she falls asleep exhausted. This happens regardless of if I'm cuddling/rocking her to sleep or if I put her in the cot awake. I thought maybe she was hungry hence the screaming but if I do offer a second feed she takes a tiny bit then falls asleep or dozes then wakes. I also thought it was because she was not yet tired and wanted to stay up- she is usually up for an hour and a half before I try to settle her but she does fall asleep eventually and the crying starts on cue around the 1.5 hour mark anyway. I also then thought maybe she's over tired as she shows minimal tired signs before the screaming so they are easy to miss. But if I put her in bed earlier she stays awake in the cot gurgling etc until the usual awake time has elapsed then screams.

Any advice? She also only really naps for 40-60 mins at a time so it seems she uses a lot of energy being hysterical for not a long time asleep. Comforting her does not help
