At 3.5 months Samy was super tiny and small but I do not know how much he weight. At 4 months he was 2.8 pounds... at 5 months he was 3.3 pounds, now at 6 months he is starting with weight at 3.6 but i think he has grown a bit more so he might be around 3.8 pounds now.
Samy is super dooper tiny though and I hope he grows more just for the safety of it
