Advice!

So my husband and I have been together for 4 years and we've been married for 2. I want another child which he says he's not against. I'm 27 (28 in april) he's 38 (39 In july) I would rather have another child while my daughter I still a bit younger and while I'm still able to keep up with a toddler and baby as well. He says he wants to wait until our communication and relationship is better( which isn't bad) I really love my husband but deep down I don't believe he wants another child but won't tell me because he knows I really do. What do I do I feel at a loss here.
