Moms of 2+, what are the biggest dos and donts for helping a new big bro/sis adjust to a new baby? What (if anything) will you do differently with this baby and your other children? DS is 2.5, but I'm sure a lot of your advice can apply to all age differences.
Re: Advice from moms of 2+ for helping big sibling adjust to baby?
Another thing is not to force them to be interested in their sibling. If they want to help out, find a way for them to age appropriately help, but if they are happy doing their own thing, making them help you only draws attention to the fact that you are busy with the baby. My MIL kept doing this with my son--she would make him stop playing to get me a diaper and "help" me change the baby, but this sort of thing just made things much more difficult. He was just two when she was born and was a very busy kid, so most times he just didn't really notice her.
Be completely truthful and talk through what you are doing when you aren't able to give them the attention they need. For example, "I am feeding baby right now, but as soon as I am done I will play with you." Instead of just "I can't right now." We really stressed the idea of taking turns with mommy and it worked out pretty well. You just have to make sure you stick to it.
Lastly, there will be a time that they both need your attention for whatever reason. You just need to accept that this is a fact of life and then basically triage the problems. Whoever needs you most gets you first and the other will have to cry/whine/fuss for a minute. I have found that they both calm down much quicker if you calm them down one at a time instead of trying to address both at the same time. What's hard to remeber in the moment is that it will not always be the baby that actually needs you first.
