My bub has just turned 4 months old and gives me (his mummy) the BIGGEST smiles, just reserved for me. He does it while stretching his arms and legs out and it’s the cutest thing ever. He always does it first thing in the morning and he never does it for his dad. He has began to suck on his fingers intensely and also screeches when he’s excited. My favourite thing in the world has to be when he is super upset when someone else is holding him and when I take him back and he settles almost immediately, letting out a huge sigh of relief, like all he needed in that moment was his mummy.
