lol! my best advice to you is to BREATH! My children are not as close in age as yours will be,but they are close enough. My daughter was 18 months when my son was born, and he was 14 months when our baby was born 4 weeks ago. I did not plan any of my kids (just like to gamble with birth control.) When we found out about each of the boys, we both freaked out a little. It was an overwhelming notion. But, that feeling passed shortly thereafter and was replaced with happiness that they would be close to each other. The only thing that still worries us, is that we feel guilty about the kids having not as much one on one parent time. But, we try to make up for that, by spending a little bit of quality alone time each day with each child. It doesn't have to be anything huge..just each of you take a child and play with them for about 15 minutes and then "swap." You can blow bubbles, cuddle, read a book, color, build blocks, or do a mini show with their stuffed animals. We put our son to bed a few minutes before our daughter, so that she has some big girl bonding time with us at the end of the night. I would also like to say that you may want to start buying diapers and wipes now! We go through about one box of wipes, and one and a half bags of diapers in any given week! Pampers has gifts to grow points..go to their website and you can sign up for this..basically, you get points for buying diapers and wipes and the points are good for toys and other products through them. I love this program..because, I am getting a special bonus for buying something that I need! The kids are going to squabble with each other..don't worry about that! Introduce the baby to the idea of a new baby now! She will understand more the older she gets and the closer to the due date of her sibling..and it makes her a part of the process. Once the new baby is here, you will figure out ways to keep the two of them close, and blend their schedules. Routine is everything! I would also suggest that you invest in a good sitter, because you and hubby are going to need dates atleast once a month to get some couple time and to have a conversation that doesn't involve talking over a fussing child or a diaper changing timeout. You can do this! Good luck!
