inter change a blanket or toy they favour , that why if you lose one you have a back up they will still like.
Don't turn on the lights when feeding at night. Feed mine by street light or dim light in room...lol Because it was not play time it was feed and go back to bed time. My sister used to stay up and play with hers and then asked how mine went back to sleep...lol
Enjoy that baby they grow up so fast that is no lie. Blink and they are a teenager.
To add to this, one tip I got when DD11 was born was that during nighttime feedings change their diaper BEFORE you feed. Oftentimes they will fall asleep while you are feeding or burping them and then you have to change their diaper after which wakes them up and then you have to get them back to sleep. Take the two minutes to change their diaper first. It worked great for me.
Every stage has its pros and cons. Enjoy the high points while they last and realize that the lows will also pass in their own time.
You do NOT have to run to a baby every time it makes a peep. Even a newborn. I'm not telling you to leave your newborn to cry for an hour straight, just that when they wake up fussing at 2 AM it's ok to give them a couple of minutes, say 5, to see if they will go back to sleep or not. It's ok. There is a world of difference between letting your baby cry for a few minutes and neglecting them.
Tummy time is crucial for brain development. As your newborn gets a little older, make sure there is plenty of tummy time.
Don't kid yourself. You absolutely CAN spoil a baby. The younger they are the harder you have to work at it but yes, you can spoil babies. Again, there is a world of difference between neglect and just not carrying them around every moment of every day and rushing to their side every time they make a peep.
Like most things in life, moderation is key. It's not good to be fanatical about any parenting practice or philosophy.
Your baby is tiny but is not as fragile as you may think. Even at this age they are resilient and you will NOT destroy your baby's life or health by making basic mistakes. They will happen. You will laugh at them later.
Like a PP said, the first time your baby sleeps through the night you will wake in a panic thinking they have died of SIDS. It's ok. We've all been there.
ETA: When DD11 was born I was also told if I put some whiskey in her last bottle every night she would sleep really good. While I'm sure that is probably true, I don't think that is actually good advice to follow.
Take each piece of advice with a truck load or two of salt.
