Sasha, firstly you do not have to wean if you TTC or fall pg. This is entirely up to you, but bfing while pg and even tandem feeding (still feeding the older one once the baby is born) is quite possible. Secondly, I have 19 months between my boys and I can tell you that I love it. But it is hard work so I think you need to be aware of that. Given that DH is keen I would think that would be a big help, surely he will help you out lots when the baby arrives (and before, being pg with a toddler can be very hard too). For me the worst thing was being so sick during pg no 2, and the odd days when one is teething and one is sick or something like that, where they both need things at the same time. The first 12 weeks or so were really tough as DS2 was very colicky. But the honest truth is that I love it and wouldn't change it for anything. The boys light up at the sight of each other, and have loved each other without jealousy since day 1. This makes me so happy, I couldn't imagine having things any other way.
