7 week old not sleeping in evening

[dileas2010]

My DS is 7 weeks old and will not sleep in evenings. He isn't sleeping much during the day either really. I think he had a growth spurt at 5 weeks and then went from sleeping all the time to very little. He's also started crying a lot so from 6 to 10 we are either consoling him and trying to get him to settle or he is wide awake. We've tried having a bit of structure with feed, bath then some shush pat in room but the only thing that really works is letting him suck little finger and that doesn't always send him off. Once he sleeps he wakes every 3 hours and it's reasonably ok to get him back to sleep after feed. Anyway, is this normal? Will it pass? Any tips on making him sleepy. Think i'm reading baby whisperer too much and worried about making him dependent on sucking and worried he's not getting enough sleep. Thanks.

The overfeeding was when he would feed for about 2 hours straight and then massively vomit - would really soak me. Wasn't too often and I eventually got to know the signs he was about to go (have whole other thread on here a few weeks ago about it).
Always known he needed an earlier bedtime was just a bit rubbish about acheiving it.... think I am more determined be more consistent as hope that will help.

Will definitely look into silent reflux - only have experience of seeing a friend's baby with reflux. He is very windy sometimes through the night and will seem to be asleep but grunts as if trying to pass wind and lots of bringing legs up as well.

Thanks for messages though and hope your DS starts sleeping longer fifitot.
