I have 3 boys: The eldest 2 are 2 yrs 10 months and 3 yrs 10 months - so they are 1 year, 1 day apart. And my third is 10 months old. They were all born in Feb! It's been tough, but we've adjusted and I've found you need 4 magical ingredients to make it work: 1. A hands-on hubby, 2. STRICT ROUTINES 3. A fabulous nanny (8am-3pm) 4. A wonderful educare (7.30-5.45pm) This way, everything is predictable for them (and us!), they know what's acceptable in terms of discipline and they all get along really well. I can honestly say there has never been a stitch of jealousy from any of them as they've never experienced (or remember) being an only child. Obviously it's not perfect: we try our best, but by the end of a weekend, the house looks like a bomb has hit! But it's little things to implement from day one: none of our kids have ever slept in our bed, they ALWAYS eat in their high chairs - still - even if it's just a sweet, AND we give them lots of attention and love - quality time reading books, talking, singing with them, going for walks, etc.
