Ökad förståelse och acceptans

Har fått en ökad kunskap och förståelse för vad som sker i utvecklingen hos små människor.
Blev lycklig mormor till tvillingflickor i april. Fantastiskt, roligt och spännande att få vara delaktig och bistå med stöd och hjälp. Två barn är TVÅ barn.
Denna app är till stöd och hjälp. Den minskar oro och ökar beredskapen att stötta både barnen och familjen under utvecklingssprången för min del.
