1st child is great, 2nd keeps you from having to entertain and spend all your focus on number one but there is jealousy, third child turns the first into a mediator between the kids and a witness to who actually did what. My kids are 15 and 17 months apart and it was so very difficult when they were little but now I line them up for everything, bathtime, hairbrushing, etc. We have a set schedule for different times of day. Once you get into the routine it's easy. On conception, it might happen right away, then again it might not, don't stress it. Stress reduces your chance of pregnancy.
