Mine are 25 months apart. At first it is super difficult. I mourned the loss of my baby, who was forced into the big sister spot. She acted out, regressed, etc. Now my newborn is almost 9 weeks old and things are better. So much so, we even started potty training again. I keep reminding myself not to feel guilty, I've just given my daughter a sister and therefore a friend for life. The dynamics of getting out of the house with all three of my children is a bit tough. But we do it, and each time it gets a bit easier. You'll be fine.
Mine are 26 mo (and 1 week) apart. DD1 would go get into trouble everytime I went to nurse DD2. I was amazed what she could get into - as in reach. Now everything possible is up. They play really well together now. DD1 regressed on PT due to a move before DD2 was born - but got it after 2 mo (Feb 08). She also refused naps for a while, but then took them again and is really too old now. I think alone time w/ the oldest is important. DD2 has been a big Mommy's girl, so DD1 has learned to love Daddy more.
Mine are 31 months apart, so not exactly like yours. Right now DS is 3 years, 4 months and dD is 9 months old. I actually found the newborn stage EASIER than I do now. sure, she wasn't sttn, but she wasn't mobile during the day and really just needed to be fed and changed throughout the day. Now, though, she is into everything and it is getting harder to look after her and my DS especially since he has some small toys, etc. It's more exhausting now in many ways, but dd is sttn so that helps a lot. it's just a bit of a trade-ff. My biggest challenge has been getting them both to nap (well,,ds does more of a "quiet time" than nap) at the same time but I am working on it. It's really not as bad as everyone says though, and each experiece is different. in the long run, it's a great age span! (like when they are 4 and 6 and they play together) GL!
