I've heard that referred to as the "witching hour." For some reason, babies tend to get fussier/high needs right around the time you're trying to get everything done in the evening - dinner, other kids homework (if you have them), etc.
We're ready to settle down for the evening, but they get fussy.
My daughter was a terrible sleeper and would fuss and cry if she wasn't being held (and not just when she was sleeping - she wanted to be held or near someone all the time). I ended up co-sleeping just to get everyone some rest. And I mean, next to me in my bed (not in a separate piece of furniture next to the bed).
Once I started "wearing" her - sling/moby - my life seemed to get easier. She just needed to comfort of being next to mom or someone else she felt safe with.
She's now nearly 17 months, and she's not clingy or needy, she doesn't still sleep with us, and she's a really happy kid, most of the time.
My advice is to figure out anything that works for both you and her, and don't worry about what it ends up being. All babies need different things - it doesn't mean they'll need them forever.
Just keep watching her cues - she'll let you know when she's ready for more independence - let her have it. Don't fight it. Don't think that you need to keep doing what's been working just because it's been working. Follow her lead in what she needs (not *wants" neccessarily).
I think what stuck with me most when I was preparing to have her and the first couple of months after she was born was that each mom and child have a unique relationship - what works for one mom/child relationship won't neccessarily work for another (even if it's the same mom).
I took that and decided to parent her the way I was most comfortable (thankfully I had the full support of my mom in whatever I chose to do). If something was working, don't worry about it. If something's not working, try something else. If something *was* working but isn't anymore, try something new.
Trust your mom instincts and you'll be fine. Don't second-guess yourself. You're her mother - you will know what is best if you listen to her and your own heart.
