Normal behaviour or could it be something else?

[Yorkie1]

Hi all
hope some of you can help shed some light on some issues we've been having with our 4wk old DS.

Started being unsettled at night, sometimes late afternoon too, at about 3wks and put it down to growth spurt or wind at first or even just normal baby behaviour! Not settling til early hours, (being awake pretty much constantly from afternoon) seemed excessively windy, crying without much break unless put on the breast-though calm while feeding unless needs winding mid feed - when put down to sleep won't settle, makes lots of grumbling/grunting sounds, spits up (though not projectile) seems to struggle to keep milk down, flails arms around and kicks blanket down with legs, fights sleep even though exhausted, hiccups quite regularly. Sure there are other things but can't think off hand. Just seems generally uncomfortable when on back sleeping though settles happily on me or DH.
Has anyone else had a lo with similar probs?
Have tried lots to help, Moses basket raised with books&carrycot (where he sleeps in daytime) keeping him upright after feeding, frequent winding, feeding little and often. Went to see osteopath last week and he mentioned ds had tight diaphram which could affect digestion. Taking him back for another session next week in the hope it helps.
Any advice / thoughts appreciated. Even if it's to tell me I'm being a paranoid mum!

(Sleep pattern wasn't regular first couple of weeks as ds was jaundice so sleepier than normal.)

Sleep patters are rarely regular when baby is this young. My experience is to go with the flow. Both my children and listening to other mums, many babies get very unsettled from about 4 in the evening. I always found it better to give them a bath in the afternoon when they are a bit happier, and just to hold them lots and feed lots in the evening. Some BF babies don't mind too much about not being winded, but others do. What helped with my second baby was to check the time he'd wake up and make sure I'd put him down 1.5 hours after he had woken up as this is as much awake time he would be happy for. Longer than that he would be really overtired.

Going out for a walk in a buggy that lies completely flat does help them settle, and fresh air does them good (and for you as well). One thing that also helped was laying him face down across my knees gently rub his back.

Sounds normal to me.

Second bathing at different times - for a long time I've gone with a bath in the morning, not the evening.

Going with the flow best way too, I think. And get a sling, put the baby in it at about half three and only remove for feeds!

And congrats on ds!
