Many congrats. It sounds like a great gap. SO much easier to have children close in age. Why go through all the hard work of having a baby, then just as it's started being more genuinely enjoyable, you're well rested and getting your energy back and the child is genuinely interesting to talk to and play with, disrupt it with a small baby again? You'll then have less fun with the older child at an age where they really can interact with you in an interesting and surprising way, and several years extension of the tiring, stressful bit. Oh, and having another baby soon after the other, I found made me less stressed about the older one and more relaxed with the younger one, for some reason, so actually improved my state of mind. Maybe it was because I felt I wasn't such an amateur mum any more!!!
This is, of course, the biased opinion of someone who adored her babies, but found it pretty tiring and restrictive (babies and toddlers don't appreciate quite the same things that adults and older children do....) and who is loving having two boys now aged 6 and 7 who can enjoy all the things together that I actually remember enjoying myself - adventure parks, interactive museums, cinema, theatre, chasing games, silly imaginative games, talking, hobbies etc, and who are close enough in age to be genuine playmates. I can now sit them both down doing the same activity together and know that I won't have to spend the whole time trying to prevent the younger one from making a mess rather than being able to give both of them proper attention. I have a much easier time, now, than friends who have children more than 2, 3 or 4 years apart, who all look much more harassed, dragging the baby around to the older child's activities and not being able to relax, knowing that their younger child still will not be able to be trusted running off on his own into the soft play area with the older one for a few more years, yet... Also, I was one of several children, with a small gap between me and my closest db and, whilst we did argue a lot as children, the close age gap definitely made us closer, emotionally, something which I valued enough to want to repeat with my own family. If you don't either have a very small gap or a very big gap, you miss some of the fun of the middle years of your child's early childhood, imo.
