Luka, 5 months

Luka was an 'easy baby' for the first 12 weeks — slept through, predictable. Toward the end of month 4 he hit the classic regression (3–4 wakings a night, short daytime naps). Now in month 5 things are settling: 5 hours unbroken at night, three daytime naps. Mum Marina is on parental leave (back in month 6) and weighing two big things: first solids (when, what, how much) and getting the nap schedule landed before her return. He breastfeeds 6–7×/day plus an evening formula bottle. He likes sitting propped, smiles but doesn't laugh out loud yet, rolls to his tummy but not always back. Two questions she can't find a clean answer to: 'is this normal for 5 months' and 'how early is too early vs too late'.
